You can also download a program called Clarify that does alot of the work of estimating changes in predicted probabilities for you. It works for logit, probit and some other fairly common models.

>I have a quick question about logit in Stata. I am running a logit regression on
>1000 observations. I save the coefficient estimates of the logit. What will be
>the most efficient way to apply the estimates to a new dataset to generate a
>new set of predicted probability for the new dataset observations?

>Thank you so much for your help! I greatly appreciate it!
