st: treatreg model with binary outcomes

[manturuk@email.unc.edu]

Hi all!

I want to run a treatment effects model.  I have binary outcome 
variables for both parts of a two-stage model.  Essentially, I have 
this:

W=Y+x1...xi+e where Y=Z+x1...x1+e
My outcome of interest is W (binary) and it is predicted by Y (binary) 
and control variables x1...xi.  Y is predicted by an instrumental 
variable Z (continuous, unrelated to W) and the the same set of control 
variables x1...xi (predictive of both W and Y).

It is my understanding that the treatreg command is appropriate only 
for a continuous outcome variable.  I have tried looking at the 
biprobit command but I have not been able to figure out if that is the 
appropriate model to use.  If so, which model gets the x1---xi 
variables?
