Re: st: Sample selection variable for bivariate probit selection

["Carlos Gamero" <gamero@uma.es>]

Dear Marteen,

In your previous messages you advice me to use heckprob command in order to 
manage the situation I describe. However, heckprob command is designed to 
correct sample selection bias when both, main regression (job satisfaction) 
and selection equation, are probit regressions. But, what happens when you 
do not have a probit as selection equation but a bivariate probit as it is 
in my case?

Thanks a lot,
Carlos
