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.


Zitat von Nick Winter <>:

See also the -adjust- command.

Hie all
How can I get predicted probabilities for differennt X values with Stata 8.0?
For example:
probit Y X1 X2 X3 X4 X5 X6
Where X2 X3 are 1/0 dummy variables and the rest are continuos variables .
I would like to estimate the predicted probability if for example X6=25
X2=0 and X1=1
Can anyone please help.
Look up the documentation for -predict- (and for -probit-), by typing

whelp predict


whelp probit

I hope this helps.
