Situations may arise when data transformation is useful. Most data transformations can be performed with the Compute command. Using this command, the data file can be manipulated to fit various statistical performances. Each salesperson’s yearly sales were predicted using multiple regression analysis. The salespeople who made $2,000 or more than their predicted values will receive a $1,000 bonus. Use the Compute command to compare the values of this year’s actual sales with the predictions from multiple regression analysis computed in the previous lesson to find eligible salespeople.

The first step in predicting who will receive a bonus is to calculate the difference between this year’s actual sales and the prediction of this year’s sales from the multiple regression analysis. Created by the ITS Training Program at CSULA for students.
