Dear all,
I want to improve my adj - R sq. I 've chequed some established models and
they introduce two times the same variable, one transformed, and the other
not. It also improves my adj - R sq.
But, isn't this bad for the collinearity? Do I interpret coefficients as
usual?
If you care about confidence interval coverage, type I error, or predictive
accuracy, trying different models in this way is not the way to go.
