Re: st: How can I get predicted probabilities for different x values after probit?

[chunkler@rumms.uni-mannheim.de]

Hi Roger, you can also downlaod Scott Long's -spost- package. The 
-prvalue- command included returns predicted probabilities and you can 
specify different x values or set x variables on their mean. -prgen- 
another command included in spost returns predicted values over the 
course of a variable for a specified x combination. Both commands work 
fine in Stata 8.

Best,
CHris
