Dear [Redacted],
short answer: I do not know! BTW, it is not clear to me why you want to tap
only my wisdom when you can have the entire list. So I am forwarding this
topic to the list for you...

Dear Martin
I would like to ask the following question.
I have used poisson regression on aggrgregated data with 2 covariates (in a
cohort of HIV positive pationts)
1.year of starting 3+ antiretroviral treatment (1997, 1998+)
2.time since starting 3+antiretrovirals (0-1, 1-2, 2+)
and I have predicted incident rates in this aggregated data using predict
option after the poisson model.
Now my question is if I want to have predicted incident rates for patints
starting 3+ arvs at 2000 and time since starting 3+ arvs , 3_4 years
is it correct to use the same predicted incident rate obtained for
aggregated data and in this example use predicted incident rate for 1998+
and 2+?
It would be graitly apreciated if you could answer my question, Please let
me know if you would like me to provid more details.
Thank you very much in advance,
Kind regards,
Shell
