Dear Dr. King,
My co-authors and I were interested in implementing a latent class
analysis using rare events data and it seems the current relogit set-up
does not allow for this. We tried to then replicate the basic relogit
procedure in SAS but ran up against the limitations of SAS's matrix
inversion capabilities. I was wondering if there is a way to program the
rare events methodology using SAS. Are you aware of such an
implementation, or a procedure in relogit that may allow us to do this?
Can you please advise us?
Regards,
Deepa Chandrasekaran
