Your Textbook Plots the Estimated Regression Function Produced by the Probit

question 21

Multiple Choice

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
