Dear all
I run a regression model with three predictors. When I try the Variance
Inflation Factors command from Rcmdr menue, I get the message
vif(LinearModel.4)
ERROR: attempt to set an attribute on NULL
and get no results. I know that there is high multicolinearity, but why does it
not work? Maybe a bug?
I use Windows Vista and everything else seems to work OK.
Thank you
