I am running some models using the SAS procedure Proc Model. The model is in a log linear form. I want to diagnose for Multicollinearity issues in the model. However, I can't find an option to diagnose Multicollinearity in Proc Model procedure unlike Proc Reg in which we can use VIF, Collin. I am using Proc model because in certain cases I need to put bounds on coeffecients, which I cannot do using proc reg.
Any help in this regard would be highly appreciated.
