Solve W&A Example 8.8 using the data in the textbook for yourself. You should come up with the answer in the textbook. (Use Data WSJ subscribers dataxISQi under Modules.) b. You computed the optimal accuracy of the discriminant analysis in part a. Suppose WSJ wants to use discriminant analysis to maximize its expected revenue. Reformulate the GA model for this objective. Is accuracy.r the best measure for this? Solve this new problem with the following data: ADVERTIZING REVENUE Predict Pos Predict Neg Actual Pos 20 0 Actual Neg -12 0
