Hi,

I'm new to Stata and am trying to run a two-step heckman where both
steps are probit. As I understand it, the command 'heckman' runs the
regression on a continuous variable for all values in step one, and
then for all nonzero values the second timei; heckprob runs it in
probit on a binary variable for the first time and then runs a regular
regression in the secnod time.

Is there a way to run a probit on one variable in the first step,  and
a probit on a different variable on the second step?  Thanks!

Andrew
