In my multiple linear regression model, all of my explanatory variables have a VIF score, lower then 3, but the highest condition index is 709. The constant and one of the explanatory variables have 1.00 variance proportion values for this condition index.
What does this mean?
According to the VIF values, my model doesn't have a multicollinearity problem, but I don't know what to do with this high condition index and 1.0 variance proportions.
