Hi, and thanks for your help

in order to do collinearity analysis I downloaded the perturb package. I run a lm (regression) and on that the ³calldiag² commad to get condition numbers but i get the following message: the variable XY with modus ³numeric² was not found (it does the same with all predictors despite all variables are numeric and exists).

Can anyone tell me how can I go arround this problem? Is there another way to have ³condition numbers²? What about VIF?

Please return message to: antoine@ruetter.ch

Thanks a lot
