Hi list,
I have a set of observations, and for each observation I have one
event date and n visit dates. How would I go about to get the date for
the last visit that occured before my event?
I'm guessing to use something like egen lastvisitdate=
rmin(eventdate-visitdate*), bu a) I'm not allowed to do that, and b) I
don't know how to only return positive values.
Hope I've been clear enough.
many thanks,
Gustaf
