Estat Vif In Stata. In my dissertation I gave evidence supporting David Belsleys work which showed that condition indexes and proportion of variance explained have some better properties but VIF is still pretty good. Given that it does work I am surprised that it only works with the -uncentered- option.
And R2 are complete the same but the results of estat vif are different. GreatSchools ratings are based on a comparison of test results for all schools in the stateIt is designed to be a starting point to help parents make baseline. This tutorial explains how to use VIF to detect multicollinearity in a regression analysis in Stata.
It is not a documented post-estimation command for logit.
Tolerance defined as 1VIF is used by many researchers to check on the degree of collinearity. You dont give any examples reproducible or otherwise of your problem. Look at the correlations of the estimated coefficients not the variables. Vif stands for variance inflation factor.
