Question

In Table 15.12 we provided estimates of the probability using the coupon in the Simmons Stores catalog promotion. A different value is obtained for each combination of values for the independent variables.
a. Compute the odds in favor of using the coupon for a customer with annual spending of $4000 who does not have a Simmons credit card (x1 = 4, x2 = 0).
b. Use the information in Table 15.12 and part (a) to compute the odds ratio for the Simmons credit card variable x2 = 0, holding annual spending constant at x1 = 4.
c. In the text, the odds ratio for the credit card variable was computed using the information in the $2000 column of Table 15.12. Did you get the same value for the odds ratio in part (b)?
