Post estimation Poisson model

[Arina Pershina]

Hello! I am performing Poisson regression, I was wondering what type of multicollinearity check is available for this regression, because it returns an error with vif

. vif

not appropriate after regress, nocons;

use option uncentered to get uncentered VIFs

r(301);

Also, what kind of post estimation is possible for the Poisson model?

[Rich Goldstein]

in general, collinearity is not an issue - is there some reason you think it might be an issue with your data?

on the second question, see

help poisson postestimation

if there is a real reason to worry about collinearity, the user-written -coldiag2- (use -search- to find and install) is, in my opinion, much better than the misnamed VIF
