Problem 6.2. Predicting Software Reselling Profits.Tayko Software is a software catalog firm that sells games and educational software. It started out as a software manufacturer and then added third-party titles to its offerings. It recently revised its collection of items in a new catalog, which it mailed out to its customers. This mailing yielded 2000 purchases. Based on these data, Tayko wants to devise a model for predicting the spending amount that a purchasing customer will yield. The fileTayko.csvcontains information on 2000 purchases. Table 6.10 describes the variables to be used in the problem (the Excel file contains additional variables).
