Essential Excel Functions for Forecasting: Your Toolkit

Okay, let’s get our hands dirty with the real tools that will transform you from an Excel novice to a forecasting whiz! We’re talking about the essential functions that are the building blocks of any good forecasting model in Excel. Think of these functions as your trusty sidekicks on your forecasting adventure.

FORECAST & FORECAST.LINEAR: Seeing the Future, Linearly!

First up, we have FORECAST and FORECAST.LINEAR. They’re basically twins separated at birth – they do the same thing, which is linear regression! Imagine plotting your historical data on a graph. Linear regression finds the best straight line that fits through those points. This line then helps us predict future values based on that straight line.

Syntax Breakdown:

=FORECAST(x, known_y's, known_x's) or =FORECAST.LINEAR(x, known_y's, known_x's)

  • x: This is the value for which you want to predict. For example, if you want to forecast sales for next month (month 13), ‘x’ would be 13.
  • known_y’s: This is the range of cells containing your dependent variable. Typically, the column with your historical data, which you are basing your forecast on. This is what you are trying to predict.
  • known_x’s: This is the range of cells containing your independent variable. Generally, the column of your historical data time units (e.g. month number, year number).

Interpreting the Results: The function spits out the predicted value based on the linear relationship it found. Higher values mean a predicted increase and lower values mean the opposite. A change in known data will also affect the line and outcome, keep this in mind.

FORECAST.ETS: Riding the Waves of Time

Next in line is FORECAST.ETS, which stands for Exponential Smoothing. This one’s your go-to function when dealing with time series data that has trends and seasonality. Think of sales data that consistently peaks in December due to Christmas. FORECAST.ETS can understand those patterns and use them to make more accurate predictions. It uses different ETS methods under the hood (like ETS.ADD for additive seasonality or ETS.MUL for multiplicative seasonality) to adapt to your data. Excel usually picks the best one automatically, but you can tweak it if you’re feeling fancy!

INDEX & MATCH: The Dynamic Duo of Data Retrieval

INDEX and MATCH are like Batman and Robin, except for Excel. They work together to dynamically retrieve data based on certain criteria. This is super handy when you need to pull in specific historical data for your forecast, like the sales figure from the same month last year.

DATE, YEAR, MONTH, DAY: Taming Time Itself

When you’re wrestling with time series data, you need to be able to manipulate dates. DATE, YEAR, MONTH, and DAY are your weapons of choice! Want to group your data by month or year? These functions can do it. Need to calculate the number of days between two dates? These are your go-to commands.

AGGREGATE: The Master of Calculations

AGGREGATE is like a Swiss Army knife for calculations. It allows you to apply aggregate functions (like SUM or AVERAGE) to your data, while also giving you the option to ignore errors or hidden rows. This is extremely useful when you need to calculate a moving average or some other aggregate statistic as part of your forecast.

IFERROR: The Safety Net

Last but not least, we have IFERROR. This function is your safety net. It allows you to handle errors gracefully in your forecasting formulas. Instead of your spreadsheet exploding with ugly error messages, IFERROR lets you specify a value to return if an error occurs. This makes your spreadsheet look professional and prevents your formulas from breaking down unexpectedly.

Example Time: Let’s say you’re dividing by zero somewhere. Instead of #DIV/0!, you can show a “0” or a “-” instead.
=IFERROR(A1/B1, 0)
In this example, if B1 is zero, the formula will return 0 instead of the error.

Pro Tip: Don’t forget to include screenshots of example formulas in your blog post to make it super clear for your readers! A picture is worth a thousand words, especially when it comes to Excel!

Excel’s Built-In Forecasting Tools: A Quick Start

  • Ever feel like you need a crystal ball to predict the future of your business? Well, while Excel can’t actually tell you what next week’s lottery numbers are, it does have a pretty nifty built-in feature called the “Forecast Sheet” that can help you make some educated guesses about what’s coming down the pipeline. Think of it as your friendly neighborhood fortune teller, but with spreadsheets instead of tarot cards!

  • The Forecast Sheet is basically Excel’s way of saying, “Hey, I know you need to predict stuff, let me help!” It’s super user-friendly, so you don’t need to be a rocket scientist (or even a seasoned data analyst) to use it. Let’s dive into how to fire it up:

    • Getting There: The magic starts in the Data Tab. Just click on it, and look for the “Forecast Sheet” button. It’s usually hanging out near the “Analyze” section. Can’t find it? Don’t worry, Excel didn’t hide it; just make sure you have some data selected first!

    • Selecting Data and Specifying the Forecast Horizon: Excel needs something to work with, so select the range of cells containing your historical data (ideally, you will have one column with dates and another with corresponding values). Once the data is selected, the Forecast Sheet dialogue box will appear. Here, you will be able to set “Forecast End Date. This determines how far into the future you want to predict. Want to see what sales might look like next quarter? Set your end date accordingly!

    • Customizing the Forecast: The best thing about it is its flexibility; You can tell it how much confidence you want in your forecast. That is, how reliable do you want it to be? And of course, you can tell excel to detect seasonality or set your own custom values if you think that will be more accurate.

  • Understanding the Output: Once you hit “Create,” Excel will generate a new sheet containing your forecast. You’ll see:

    • Historical Data: The original data you used to generate the forecast, so you can compare it with predicted data.
    • Forecast Values: These are the predicted values for the future time periods you specified.
    • Confidence Intervals: It represents the range of values within which the actual values are likely to fall. The narrower the interval, the more confident you can be in the accuracy of the forecast.

Understanding Statistical Concepts: Laying the Foundation

Forecasting in Excel isn’t just about clicking buttons; it’s about understanding the story your data is trying to tell. Think of it as being a data whisperer! To truly master forecasting, you need to get cozy with some fundamental statistical concepts. Don’t worry; we’ll keep it light and fun!

Key Statistical Concepts

  • Time Series Analysis: This is all about data points indexed in time order. A time series is any sequence of data that is recorded over regular time intervals. These intervals might be as short as a second, or as long as a year (or even longer!) The importance of time series data is that the passage of time matters. Things can change, so you need to account for these changes when forecasting.

  • Trend: This is the general direction your data is heading. Is it going up, down, or staying flat? Spotting the trend is like reading the title of the story your data is telling. Is your business’s profit going up, down, or flat? Is the number of users on your website increasing or not? If it is a straight line, we call that a linear trend. But the trend might be more complex, for example, rising, falling, then rising sharply.

  • Seasonality: This refers to patterns that repeat at regular intervals, like clockwork. Think of ice cream sales spiking in the summer or holiday shopping bonanzas in December. Recognizing seasonality helps you anticipate these predictable bumps and dips. Seasonality can make forecasting a little difficult, especially for shorter-term sales periods.

  • Moving Average: Imagine smoothing out a bumpy road. That’s what moving averages do for your data. It helps to filter out those random blips and make the underlying trend clearer. This means you don’t overreact to the ups and downs you would see with traditional forecasting.

  • Exponential Smoothing: Now, this is where things get a tad more sophisticated. Exponential smoothing is like a fancy moving average that gives more weight to recent data. It’s useful for time-based data, like when forecasting sales or website visits. It means you can forecast using time-based data and not rely solely on historical data.

  • Regression Analysis (Basics): Want to find out how different factors are influencing each other? Regression analysis helps you do just that! While it can be complex, the basic idea is to understand how changes in one variable (like marketing spend) affect another (like sales). The basic idea is that the higher your budget for marketing the higher your business sales will be.

Forecast Accuracy Metrics

  • Mean Absolute Deviation (MAD): This tells you, on average, how far off your forecasts are. It’s like saying, “On average, my forecast is off by this much.”

  • Mean Squared Error (MSE): MSE squares the errors before averaging them, which makes larger errors stand out even more.

  • Root Mean Squared Error (RMSE): RMSE is the square root of MSE, which puts the error back in the original units of your data. It’s often easier to interpret than MSE.

Applying Concepts in Excel

Excel isn’t just a spreadsheet; it’s a forecasting playground! Understanding these statistical concepts allows you to choose the right Excel functions, interpret the results correctly, and fine-tune your forecasting models for maximum accuracy. It also will help you select the right charts and graphs to showcase the data from your business.

Data Preparation: Cleaning and Transforming Your Data

Okay, let’s talk about the not-so-glamorous but absolutely essential part of forecasting: data prep. Think of your data as the ingredients for a delicious forecast. Would you bake a cake with rotten eggs? Probably not (unless you’re going for a very avant-garde culinary experience).

The same principle applies here!

Why is it so important? Because, garbage in, garbage out. A fancy forecasting model won’t save you if your data is a mess. It’s like trying to build a skyscraper on a foundation of sand.

So, how do we whip our data into shape? Let’s break it down:

Spotting and Squashing Errors

Think of yourself as a data detective, hunting down those sneaky errors!

  • Typos: Those pesky little mistakes that can throw everything off. TRIM function to the rescue! It helps to delete any rogue spacing in your data, e.g. TRIM(A1).
  • Inconsistencies: Make sure your units are the same. You can’t mix apples and oranges (or, you know, kilograms and pounds). The SUBSTITUTE function is your friend. Need to replace “Inc.” with “Incorporated”? SUBSTITUTE(A1,"Inc.","Incorporated") will do the trick.
  • Outliers: Extreme values that don’t fit the pattern. Investigate them! Are they legitimate, or are they errors? If they’re errors, fix them or exclude them.

Taming Missing Values

Empty cells staring back at you? Don’t panic!

We have a couple of strategies here:

  • Imputation: Filling in the gaps with estimated values. You could use the average, median, or even a more sophisticated method like linear interpolation.
    • Pros: Keeps your dataset complete.
    • Cons: Can introduce bias if not done carefully.
  • Interpolation: Like connecting the dots! Excel can estimate the missing values based on surrounding data points.
    • Pros: Maintains data integrity.
    • Cons: May not always be accurate, especially with volatile data.
  • Ignoring Them: Yes, you can sometimes just leave them out!
    • Pros: Doesn’t add bias and is fast
    • Cons: Depending on the dataset, you can loose a lot of data if the missing data is frequent.

Data Transformation: Making it Play Nice

Sometimes, data just isn’t in the right format for forecasting. That’s where transformation comes in.

  • Aggregating data: You might need to summarize daily sales data into monthly totals. Use PivotTables!
  • Creating Time Series: Converting your data into a time-based format that Excel can understand. Make sure your dates are formatted correctly!
  • Converting Data: You can use the VALUE Function to help converting data to appropriate format.

With a little data prep magic, your forecasts will be accurate!

Working with Time-Related Entities: Dates, Months, and More

Okay, so you’ve got your data, and it’s all about time—sales figures, website visits, the number of times your cat demands food (okay, maybe not that one). But how do you actually wrangle those dates and turn them into something useful for forecasting? Let’s dive in! Think of Excel as your trusty time-traveling DeLorean, ready to whisk you through months, years, and even custom intervals. No plutonium required!

Monthly Magic: Summing Up Your Successes

First up, let’s talk about months. You probably want to know how your business performs each month, right? So, let’s group our sales date by month. In Excel, use the MONTH function combined with SUMIF or a PivotTable. Imagine telling Excel, “Hey, find all the entries from January, and add them up!” Suddenly, you’ve got monthly totals, ready to fuel your forecasts!

Yearly Overviews: Seeing the Big Picture

Now, zoom out! What about the year as a whole? For yearly data, use the YEAR function in the same way you used MONTH. Group your data and SUMIF or use PivotTable to generate the totals. This is perfect for spotting long-term trends or seeing if 2024 is going to be the year you finally conquer the world (or at least hit your sales targets!).

Quarterly Quests: Breaking Down the Year

Feeling a bit more granular? Let’s tackle quarters. Since Excel doesn’t have a direct “Quarter” function, you can use nested IF statements or a clever bit of math with the MONTH function. The formula basically says, “If the month is January, February, or March, then it’s Quarter 1. If it’s April, May, or June, it’s Quarter 2,” and so on. It looks a bit intimidating at first, but once you’ve got it, you’ll be slicing and dicing your data like a pro chef! It is good for creating time series models.

Custom Time Intervals: Your Data, Your Rules

Want to get really specific? Need to analyze data by week, bi-week, or some other custom interval? This is where things get interesting! You can use the INT function combined with your date values to create week numbers. The key is to find a formula that converts a date into a unique number for your chosen interval. Or use PivotTable to group into the week.

EOMONTH: Your Secret Weapon for Time-Based Calculations

And finally, let’s talk about EOMONTH. This function is your secret weapon for anything involving the end of the month. Need to calculate payment deadlines or forecast based on month-end figures? EOMONTH is your new best friend!

So, there you have it! By mastering these techniques, you’ll be able to bend time to your will (well, sort of) and create amazing, accurate forecasts in Excel! Now go forth and conquer those time-based challenges!

Forecast Parameters and Settings: Fine-Tuning Your Model

Okay, so you’ve got your data, you’ve got your Excel sheet, and you’re ready to predict the future! But before you hit that “Forecast” button and call it a day, let’s talk about those little knobs and dials – the forecast parameters. Think of it like tuning a guitar; a little tweak here and there can make all the difference between a beautiful melody and a cat screeching! So, let’s see what you’ve got in front of you.

Forecast Start Date: When Does the Crystal Ball Activate?

This is the big one. Where do you want to look into the future of the data? It is just what it sounds like: it tells Excel exactly when to start predicting values. If you set it wrong, you might be forecasting for last Christmas when you need to know about next Easter. To set this date you can change its cell in the setting. The most common setup is to set it to one day later than the last date with data that is already there. Easy as pie!

Confidence Interval: How Sure Are We, Really?

Ever heard someone say, “I’m 99% sure it’s going to rain tomorrow”? That’s a confidence interval in action! In Excel, this tells you the range within which the actual values are likely to fall. A wider interval means you’re less confident, but more likely to be right. A narrower one means you’re more certain, but more likely to be wrong! Setting it depends on how willing you are to take risks. If you’re forecasting sales and need to order enough inventory, you might want a wider confidence interval, just to be safe! The default is 95% but feel free to move those percentages around according to your requirements.

Seasonality Detection: Is It Just the Weather, or Is It Something Else?

Does your data have a rhythm? Maybe sales always spike in December, or website traffic dips every Sunday. That’s seasonality, baby! Excel is usually pretty good at spotting these patterns on its own, but sometimes it needs a little nudge. If Excel’s missing something you can change it manually. For example, if you know there’s a weekly pattern but it is not being correctly picked up set it manually. Think of seasonal patterns as the ghost in the machine of data, it is good if you know how to manipulate the data to your advantage.

Fill Missing Points: Patching Up the Holes in the Data

Life happens, and sometimes your data has gaps. Maybe the server crashed for a day, or someone forgot to enter the numbers. No sweat! Excel can fill in those missing pieces using interpolation. There are several interpolation methods, each with its pros and cons:

  • Linear Interpolation: Imagine drawing a straight line between the two points on either side of the gap. This method is simple and works well if the data has a fairly consistent trend.

  • Non-Linear Interpolation: This is usually the standard Excel uses because it guesses the curve using existing data around the gaps that need to be filled.

Choosing the Right Settings: It Depends!

There’s no one-size-fits-all approach to forecasting. The best settings depend entirely on your data and what you’re trying to predict.
* Stable Data, Clear Trend: You can use lower confidence interval and let the software pick the seasonality
* Unpredictable data: You should focus on raising the confidence interval to predict data that is likely to happen.
* Erratic: You need to pick the interpolation that better adjusts to all the circumstances.

So, play around with those parameters, see what works best for you, and don’t be afraid to experiment! With a little tweaking, you’ll be forecasting like a pro in no time.

Evaluating Forecast Accuracy: Measuring Your Success

Alright, you’ve built your forecast, but how do you know if it’s any good? It’s like baking a cake – looks delicious, but does it taste good? Evaluating forecast accuracy is super important because it helps you understand just how reliable your predictions are. Think of it as giving your forecast a report card!

Why Bother Evaluating?

  • Reality Check: Confirms your forecast is grounded in reality, not just wishful thinking.
  • Model Comparison: Helps you compare different forecasting models and pick the one that performs best.
  • Continuous Improvement: Provides insights for refining your forecasting techniques over time.

Decoding Accuracy Metrics in Excel

Now, let’s get down to the nitty-gritty. Excel can do the heavy lifting in calculating these metrics. Here’s the lowdown on a couple of key players:

  • Mean Absolute Error (MAE):

    • Calculation: The average of the absolute differences between your forecasted values and the actual values.
    • Interpretation: Tells you, on average, how far off your forecasts are. For example, an MAE of 10 means your forecasts are, on average, 10 units away from the real numbers. Lower is better here, folks!
  • Root Mean Squared Error (RMSE):

    • Calculation: A bit more complex—it squares the differences between forecasted and actual values, averages them, and then takes the square root.
    • Interpretation: Similar to MAE, but gives more weight to larger errors. This one is handy when you really want to avoid big misses. Again, a lower RMSE indicates better forecast accuracy.
  • Excel steps to perform the calculation:
    • Import: Import your forecast data into excel
    • RMSE Formula: In an empty cell, write this formula “=SQRT(SUMSQ(B2:B7-C2:C7)/COUNT(B2:B7))”
    • MAE Formula: In an empty cell, write this formula “=AVEDEV(B2:B7,C2:C7)”
    • Hit Enter: This displays the value in the cell

Picking the Best Model

Alright, you’ve got your accuracy metrics for different models. What now? Easy—compare them!

  • Smaller is Better: The model with the lower MAE and RMSE is generally the better choice.
  • Consider Context: Think about what type of errors you’re most concerned about. If large errors are a big no-no, RMSE might be more important.
  • Excel is Your Friend: Use Excel to create charts comparing the accuracy metrics for different models. A visual comparison can make the choice even clearer.

By evaluating your forecasts, you’re not just crunching numbers; you’re turning insights into actionable improvements to your forecasting process. Happy forecasting!

File Formats and Data Sources: Importing and Exporting Data

Okay, so you’ve got your Excel sheet ready to forecast, but what if your data is chilling somewhere else? No sweat! Let’s talk about how to get that data into Excel (and out, if needed).

File Formats: The Language of Data

  • .xlsx: Ah, the good ol’ reliable Excel format. It’s the default, it’s what you see every day, and it handles all your fancy formatting and formulas. It’s like the English language of spreadsheets.

  • .csv: Think of this as the universal translator for data. Comma-separated values. It’s a plain text file, but don’t let that fool you. It’s supported by basically every data tool out there. If you’re sharing data between different programs, CSV is your best friend.

Importing Data: Gathering Your Intelligence

So, your data isn’t already in Excel? No problem. Excel’s got some serious importing skills. Think of it as your own personal data spy.

  • External Data Sources: This is where things get interesting. Imagine your sales data is locked away in a SQL Server database, or maybe you’ve got customer info in an Access database. Fear not! Excel can reach out and grab that data.

    • Databases (e.g., SQL Server, Access): Excel can connect directly to these databases and pull in the data you need. You might need to know a little SQL (the language of databases), but Excel makes it pretty straightforward with its built-in wizards.

    • Text Files: Those .txt files with columns of information can feel daunting. But Excel? It eats them for breakfast!

    • Web Data (using Power Query): This is where Excel becomes a superhero. Power Query is a tool that lets you grab data from websites. Need stock prices? Want to pull in data from a Wikipedia table? Power Query’s got you covered.

    • Power Query: Your Data Transformation Sidekick: A quick shoutout to Power Query. It’s like a data cleaning wizard. It allows to reshape, filter, and transform your data before it even hits your spreadsheet. This is HUGE for ensuring your forecasts are based on clean, consistent data. You can find it under the “Data” tab, usually grouped with “Get & Transform Data” or “Get External Data”. Give it a try and see how it can simplify your data wrangling!

Charting and Visualizing Forecasts: Telling the Story

Alright, buckle up, data detectives! You’ve crunched the numbers, wrestled with formulas, and now it’s time to unveil your forecasting masterpiece! But let’s face it, staring at a spreadsheet full of numbers can be about as exciting as watching paint dry. That’s where charting and visualization come in! Think of charts as the superheroes of data – they swoop in and transform boring numbers into eye-catching stories that everyone can understand. We’re not just making charts, we’re turning data into insights.

And when it comes to forecasting, there’s no better hero than the humble Line Chart. Forget the fancy 3D pie charts that look like abstract art – line charts are your bread and butter for showing trends and patterns over time. They’re like a visual time machine, letting you see where your data has been and where it’s headed!

Let’s get down to brass tacks and build our own forecasting story, step-by-step, right inside of Excel:

How to Create a Line Chart in Excel for Forecasting

Okay, grab your mouse and let’s get charting. Don’t worry, it’s easier than parallel parking!

  • Selecting the Data Range: First things first, highlight the data you want to chart. Make sure your time periods (dates, months, years) are in one column, and your actual values and forecasted values are in another. Think of it like choosing the actors for your movie – you need the right players for the story to make sense. Click and drag your mouse over the range you want to use.
  • Choosing the Line Chart Type: With your data selected, head to the “Insert” tab on the Excel ribbon. Look for the “Charts” section and find the “Insert Line or Area Chart” option. Click the dropdown arrow, and you’ll see a bunch of different line chart options. For forecasting, a simple “Line” chart or a “Line with Markers” chart is usually your best bet. Pick the one that tickles your fancy!
  • Adding Chart Titles and Axis Labels: No one wants to stare at a chart without knowing what it’s showing. Click on your chart and then go to the “Chart Design” tab. From there, you’ll want to “Add Chart Element.” In the dropdown, there are lots of options, but focus on “Axis Titles” and “Chart Title”. Give your chart a descriptive title that summarizes the forecast (e.g., “Projected Sales for Q3 2024”). Label your axes clearly (e.g., “Months” on the horizontal axis, “Sales (in $)” on the vertical axis). Think of it as putting a catchy headline and informative captions on a news article – it helps people understand what’s going on!
  • Don’t forget the Key thing is to give the reader insight into what the chart shows.

Customizing Charts: Polishing Your Presentation

Alright, you’ve got your forecast, you’ve got your chart…but does it pop? Does it tell a story that even your goldfish could understand? Probably not…yet. This is where the magic happens, where you transform a bland spreadsheet visual into a compelling narrative.

Think of customizing your charts like giving your data a makeover. We want eye-catching and easy-to-understand, not just ‘meh, there’s the data.’

First things first, let’s dive into the Chart Tools Design Tab. It’s like the control panel for your chart’s aesthetic destiny.

  • Accessing the Chart Tools Design Tab:

    Click on your chart and watch the magic unfold! (Okay, maybe not magic, but the Design and Format tabs will appear in the ribbon). This is where you can quickly change your chart type, add chart elements (titles, axis labels, legends), choose a chart style, or filter your data.

    • Quick Layouts: Under the Design tab, explore the Quick Layouts for pre-designed chart layouts that include common chart elements. This saves you time and provides a good starting point for customization.
    • Chart Styles: Browse the Chart Styles gallery for different visual styles. Hover over each style to preview it on your chart. This is a fast way to change the overall look and feel.

Next up, let’s get technical with Trendline Options:

  • Adjusting Trendline Options:

    Trendlines are your best friends when it comes to spotting patterns and making predictions. Right-click on your data series in the chart, choose “Add Trendline,” and get ready to tweak.

    • Trendline Types: From linear to exponential to polynomial, pick the trendline that best fits your data. If you’re not sure, experiment!
    • Display Equation on Chart: Want to show off your mathematical prowess? Display the trendline equation right on the chart.
    • Display R-squared Value on Chart: This tells you how well the trendline fits your data. The closer to 1, the better.

Finally, let’s talk about the fun part: Formatting Chart Elements

  • Formatting Chart Elements:

    This is where you get to unleash your inner artist.

    • Colors: Make your chart visually appealing by changing the colors of your data series, axis labels, and chart background. Use a color palette that is easy on the eyes and complements your data.
    • Fonts: Choose fonts that are readable and consistent throughout your chart. Avoid using too many different fonts, as this can make your chart look cluttered and unprofessional.
    • Line Styles: Adjust the thickness and style of your lines to emphasize key data points. Use different line styles to distinguish between different data series.
    • Titles and Labels: Add clear and concise titles and labels to your chart to help your audience understand the data. Use descriptive labels for your axes and data series.

Best practices for creating visually appealing and informative charts:

  • Keep it Simple: Don’t overload your chart with too much information. Focus on the key insights you want to convey.

  • Label Everything: Axes, data series, you name it. Make sure everything is clearly labeled so your audience knows what they’re looking at.

  • Use Color Wisely: Color can be a powerful tool, but don’t go overboard. Use a consistent color scheme that is easy on the eyes.

  • Tell a Story: Your chart should tell a story. Highlight the key takeaways and make it easy for your audience to understand the data.

So, go forth and customize! Your data deserves to shine, and with a little bit of effort, you can create charts that are both informative and visually stunning.

So there you have it! Forecasting in Excel doesn’t have to be a headache. With these tips, you’re well on your way to making smarter decisions and seeing into the future—or at least, making a pretty good guess. Happy forecasting!
