![]() ![]() This is done in cases where there is no meaning in the model at some value other than zero, zero for the start of the line.

The regression analysis in Excel estimates the relationship between a dependent variable and independent variables using the least-squares regression method. You can enter an actual name, such as price or income in a demand analysis, in row one of the Excel spreadsheet for each variable and it will be displayed in the output.
