Random forests prediction
Hi all,
I have a strange problem when applying RF in R.
I have a set of variables with which I obtain an AUC of 0.67.
I do have a second set of variables that have an AUC of 0.57.
When I merge the first and second set of variables, the AUC becomes 0.64.
I would expect the prediction to become better as I add variables that do
have some predictive power?
This is even more strange as the AUC
