Question: 13. Investigate the relationship between cutoff values (01) and misclassification error rates for the predicted probabilities using the logistic model used in Review Problem 12.

13. Investigate the relationship between cutoff values (0–1) and misclassification error rates for the predicted probabilities using the logistic model used in Review Problem 12.

(from 0 through 1).

(b) What would be a reasonable cutoff value that minimizes both class 0 and class 1 classification errors.
