For a binary response y, let ỹ be the proportion of ones in the sample (which is equal to the (i) sample average of the y,). Let ĝo be the percent correctly predicted for the outcome y = 0 and let 9, be the percent correctly predicted for the outcome y = 1. If p is the overall percent correctly predicted, show that p is a weighted average of ĝo and q1: p = (1 – y)ao + 5ª1- (ii) In a sample of 300, suppose that ỹ = .70, so that there are 210 outcomes with y, = 1 and 90 with y; = 0. Suppose that the percent correctly predicted when y = 0 is 80, and the percent correctly predicted when y = 1 is 40. Find the overall percent correctly predicted.
