Here’s a breakdown of what each piece of information in the output means: EXCEL REGRESSION ANALYSIS OUTPUT PART ONE: REGRESSION STATISTICS. These are the “Goodness of Fit” measures. They tell you how well the calculated linear regression equation fits your data. Multiple R. You can create a regression equation in Excel that will help you predict customer values. To create a regression equation using Excel, follow these steps: Insert a scatterplot graph into a blank space or sheet in an Excel file with your data. You can find the scatterplot graph on the Insert ribbon in Excel 2007 […] Using Excel’s built in trendline function, you can add a linear regression trendline to any Excel scatter plot. Inserting a Scatter Diagram into Excel Suppose you have two columns of data in Excel and you want to insert a scatter plot to examine the relationship between the two variables. Multiple Linear Regression in Excel You saw in the pressure drop example that LINEST can be used to find the best fit between a single array of y-values and multiple arrays of x-values. In that example, we raised the x-values to the first and second power, essentially creating two arrays of x-values. Multiple regression analysis was used to test whether certain characteristics significantly predicted the price of diamonds. The results of the regression indicated the two predictors explained 81.3% of the variance (R 2 =.85, F(2,8)=22.79, p<.0005). It was found that color significantly predicted price (β = 4.90, p<.005), as did quality (β = 3.76, p<.002).
