Subject: st: Get a probability response curve after probit/logit regression?
Hi, everyone:
I have a probit model like the example in Greene's book : probit grade gpa
psi tuce
How can I get a probability response curve after the probit regression?
more specifically, x is the gpa; y is Prob(grade=1), two curves (one with
PSI, another without PSI) are what I need,
then the effect of PSI on Predicted Probabilities can be compared.
Many thanks.
Fiona
