st: Heckman/2SLS

["Daniel" <methdunk@hotmail.com>]

Hi Stata Users

I want to incorporate sample selection bias using the Heckit model in a 2SLS
model.

I am unsure how to adjust the standard errors in the 2SLS model to account
for sample selection bias (do I need to do this?), in addition to including
the inverse mills ratio as a regressor.

Thanks

Daniel
