Hi all!
I'm a very new user of Stata and it's wonderful! I'm working with panel data and I'm also new in that. I would like to know how to check for multicollinearity among variables.
I know the corr comand, but this is not for panel data (unless you work in wide format, but in that case I'm not sure if the results are very good). Then I can use xtcorr, but this should be used after xtgee and I think that the spirit then is to check correlations among residuals, not correlations among variables.
Can someone help me and give me a hint on how to check correlations among variables before start working?
Thanks for your help!
Sincerely,
Tomas
