Hi,
I have a question concerning predicition after performing a heckman estimation :
Do I have to calculate and add the mills ratio after having predicted (after using "heckman" or does the stata command "predict, xb" (after "heckman") automatically adjust for that, so that my results are unbiased?
thank you for your advise
cheers,
peter
