Thanks so much for the reply it was exceptionally helpful! A couple of questions:

  1. I was under the impression that k-fold with B=10 would train on 9/10, validate on 1/10, and repeat 10 times for each different 1/10th. Is this how the procedure works in R?
  2. Is the reason you recommend repeating k-fold 100 times because the partitioning is random, ie not 1st 10th, 2nd 10, et cetera so you might obtain slightly different results?
