Dear all,
I have been using rpart to get trees. May someone help me with how I can do some logistic regression modelling to derive odds ratios on the branches. Also help on how to derive estimates on prediction error. -- Kind Regards, Jestinah
The odds ratios from rpart will be badly biased away from 1.0. Unbiasing them will be tricky. Frank
