Subject: diagnosis of multicollinearity in event history analysis
I know when i run regression with proc reg, I can ask for collinearity
diagnosis statistics such as VIF and condition index, to see whether I
have multicollinearity problems. But when I am using proc phreg, how can
I get these? Or there are different ways to test for multicollinearity?
Thank you very much.
