Hello everyone
I need some help with Heckman twostep treatment model. As I know that inverse mills ratio is to ensure the existence of endogenous. I can get Lambda directly when I run Heckman using code" etregress", but some one told me that the Lambda from the results is just Inverse mills ratio. so is this true? Many thanks.
