Hello,
I am interested in estimating separate Cox regression models for 2
groups of individuals- trainees and non-trainees. The problem is that the
training decision is endogenously determined, so that the differences
between the 2 sets of parameter estimates may well be driven by the
differences in the unobservable characteristics between the 2 groups of
respondents. Is there a way to correct for this in Stata?
