• Select the “Y” or dependent variable of the model, which is “Q,” and highlight the array of data for “Q”

• Next, select the independent variables in the model “PAL, M INCOME, P, and PBMAC,” by highlighting that array of data. When selecting both the dependent and independent variables it is best to include the data labels Q, P, M, etc. in your arrays. Before proceeding with running the regression, click the label checkbox, if you included the labels in your data array.

• Unless otherwise specified, your output will go to a new worksheet. If you would like to keep the output on the same worksheet click on “Output Range” and specify the area you want the output to be placed.
