How do I measure multicollinearity in Proc MIXED?

[marcioadg]

In Proc GLM is ok to use the VIF but in MIXED there is no Rsq.

Multicollinearity is a dependency in the X matrix.  Any of the procedures that calculate VIF can be used to get a measure of multicollinearity--PROC REG probably is the most appropriate due to the richness of options.  See the responses in the thread:

Try using COLLIN also as option in GLM.
