Dear Janet,

It sounds like you may be referring to a Cragg-type double hurdle model,
where the probit determines whether the censored dependent variable can
be observed or not. 

If this is indeed the case, I have coded this and it can be downloaded
at the following site:

Hope that this is what you are looking for.

Julian

Hello,

Does anyone know how I can estimate a simultaneous equation of a tobit
and a 
probit in Stata? That is, instead of a bivariate probit, do a similar 
estimation but for a tobit and probit equation. I read something like
that 
in a World Bank Review paper but I am not sure how do the estimation.

Thanks.
Janet
