st: biprobit with sample selection
Is possible to combine biprobit with sample selection
I want to estimate a model:

remain) for a welfare recipint sample. Y2 is binary
dummy explanatory variable (married or single) in (1)
but could be endogenous to Y1. I want to address the
endogeneity issue of Y2 in eq (1). So I use the
But the complex issue is when I estimate equation (2)
only among welfare recipents, it has a sample
selection issue should be addressed by Hekcman
So I wonder how to combine biprobit with sample
selection in Stata.
Thanks so much for any help!
