I also use the very same strel2, and from looking at your code, you have not
set up stset correctly, namely I would replace with
stset ageexit, failure(status=1) origin(aadx).
Also so I am not sure that adding 0.0001 onto age exit when ageexit=aadx is
wise, given that ons would normally exclude if age at exit = age at
diagnosis.
Anyway hope this helps,
