◆ PrepareFoldDataSet()

void TMVA::CvSplit::PrepareFoldDataSet ( DataSetInfo dsi,

Set training and test set vectors of dataset described by dsi.

[in]dsiDataSetInfo for data set to be split
[in]foldNumberOrdinal of fold to prepare
[in]ttThe set used to prepare fold. If equal to Types::kTraining splitting will be based off the original train set. If instead equal to Types::kTesting the test set will be used. The original training/test set is the set as defined by DataLoader::PrepareTrainingAndTestSet.

Sets the training and test set vectors of the DataSet described by dsi as defined by the split. If tt is eqal to Types::kTraining the split will be based off of the original training set.

Note: Requires MakeKFoldDataSet to have been called first.
