Hae guys,
When performing a poisson regression sometimes one has to input the
offset/exposure variable to account for individual time spent in a certain
therapy before acquiring a certain condition of interest, whereby in r
offset(log(months)) and in STATA offset(log(months)) results differ.
Thereby increasing the difference of the overall outcome, i don't know why
any one know why?
