Hi,
I need to estimate a probit with a continous variable in the RHS that
it is only observed when the binary outcome is 1. I first estimate
the continuous variable with those observations where there is no
censoring and estimate predicted values for all the observations.
(Selection is random)
Then I set the predicted value for all observations in the RHS to
estimate the probit and correct standard errors (Topel-Murphy) for
the fact I include an estimated variable in the model.
How may I estimate both equations jointly (or recursively) and
efficiently instead of in two-stages?
Thank you,
Marian
