3. The logit regression of mortgage deny against the P/I ratio and black using 2380 observations yields the estimated regression function: Pr (deny = 1 P/Iratio, black) = F(-4.25 + 5.33P/I ratio + 1.32black (0.38) (0.95) (0.17) 1) If P/I ratio =0.5, what is the probability that a black applicant will be denied? (5%) 2) Compare the linear probability, probit, and logit models regarding the estimated probabilities. (10%)
