This is similar to question Caret re-sampling methods, although that really never answered this part of the question in an agreed upon way.
caret's train function offers
repeatedcv. What is the difference in say doing:
MyTrainControl=trainControl( method = "cv", number=5, repeats=5 )
MyTrainControl=trainControl( method = "repeatedcv", number=5, repeats=5 )
cv breaks the set into k-folds (parameter
number), and then starts over and runs it parameters
repeats number of times.
The only thing I could think of is that maybe regular
repeats uses the same exact indexes for the folds each time? essentially running the
cv on the same exact folds each time, vs perhaps
repeatedcv selects new folds each times?
Can someone clarify?
