I'm new to R and to validation of logistic regression models via bootstrapping.
I see that there are various approaches to bootstrapping, and I am wondering
(1) which approach would be best for internal validation of predictive
discrimination, (2) are there any good resources that could be recommended to
explain the optimal approach, and (3) what packages in R should I use to
achieve this approach. Many thanks for the input.
