Increase number of folds for TMVACrossValidation

TMVA
1

Hi,

I’m checking the TMVACrossValidation with the example code in tutorial/tmva.
The output results is
Summary for method BDT
Fold 0: ROC int: 0.968758, BkgEff@SigEff=0.3: 0.976
Fold 1: ROC int: 0.965505, BkgEff@SigEff=0.3: 0.975
Is it possible to have more folds?

Thanks!

Best,
Jung

Hi!

Sorry I have another question about cross validation.

May I ask what is the results of “GetEff30Values()” function?
I did not found description on the user guide.

Thanks.
