Excel -- PART IV Linear Regression Analysisrev
The Linear Regression function in Excel calculates the coefficients (slope and intercept) of the line that minimizes the sum of squared differences between the actual values and the predicted values. This line is also known as the "regression line" or "trendline." Free Download Part 2. How to...
We can chart a regression in Excel by highlighting the data and charting it as a scatter plot. To add a regression line, choose "Add Chart Element" from the "Chart Design" menu. In the dialog box, select "Trendline" and then "Linear Trendline." To add the R2value, select "More Trend...
