Dear Maarten,

Thank you very much for your reply. I used Heckman (1981) methods to
correct the initial conditions problem in a dynamic xtprobit model
based on a panel data. There is no built-in command in Stata 10 which
enables me to apply the Heckman's method. So, I used -redprob-
(Stewart,2006) to estimate the model. Could you help me to estimate
probabilities after the model, maybe, the syntax of 'pu0'?

Thank you very much.

Yu

If you have Stata 10 you should use the official -xtprobit- command,
which will allow you to use -predict, pu0-
