Your textbook plots the estimated regression function produced by the probit regression of deny on P/I ratio The estimated probit regression function has a stretched "S" shape given that the coefficient on the P/I ratio is positive. Consider a probit regression function with a negative coefficient. The shape would
A) resemble an inverted "S" shape (for low values of X, the predicted probability of Y would approach 1) B) not exist since probabilities cannot be negative C) remain the "S" shape as with a positive slope coefficient D) would have to be estimated with a logit function
