It lies between -1 and 1, and its absolute value depicts the relationship strength with a large value indicating a stronger relationship, a low value indicating negative and zero value indicating no relationship.

Method #2 – Analysis ToolPak Add-In MethodĪnalysis ToolPak is sometimes not enabled by default, and we need to do it manually. If the graph gets plotted in reverse order, then either switch the axes in a chart or swap the columns in the dataset. Note: In this type of regression graph, the dependent variable should always be on the y-axis and independent on the x-axis. We can improvise the chart as per our requirements, like adding axes titles, changing the scale, color and line type.

If you need to, you can adjust the column widths to see all the data.You can download this Linear Regression Excel Template here – Linear Regression Excel Template Method #1 – Scatter Chart with a Trendline For formulas to show results, select them, press F2, and then press Enter. The equation for FORECAST and FORECAST.LINEAR is a+bx, where:Īnd where x and y are the sample means AVERAGE(known_x's) and AVERAGE(known y's).Ĭopy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. If the variance of known_x's equals zero, then FORECAST and FORECAST.LINEAR return the #DIV/0! error value. If known_y's or known_x's is empty or one has more data points than the other, FORECAST and FORECAST.LINEAR return the #N/A error value. If x is nonnumeric, FORECAST and FORECAST.LINEAR return the #VALUE! error value. The data point for which you want to predict a value. The FORECAST/FORECAST.LINEAR function syntax has the following arguments: You can use these functions to predict future sales, inventory requirements, or consumer trends.

The existing values are known x-values and y-values, and the future value is predicted by using linear regression.

The future value is a y-value for a given x-value. DescriptionĬalculate, or predict, a future value by using existing values. It's still available for backward compatibility, but consider using the new FORECAST.LINEAR function instead. The syntax and usage of the two functions are the same, but the older FORECAST function will eventually be deprecated. Note: In Excel 2016, the FORECAST function was replaced with FORECAST.LINEAR as part of the new Forecasting functions.
