Dear all,
I'm running poisson regression model in Stata 9, but the value of
Pseudo R2 is missing. Does anyone know how to deal with this?
Thanks.
H.
What is the actual command you are typing, and in particular, what options
are you using? Sometimes stats reported change depending on whether you
are using svy or robust or whatever. Showing the printout might help. I
just ran a simple poisson regression and got pseudo R2, so I assume the
problem is related to the options you are using or maybe something about
your data.
