models. Defaults to |
Partitions the data set into training and test set according to the specified fraction. The training and test index sets are added to the original data and returned. If requested, the distribution of the best algorithms in training and test set is approximately the same, i.e. the sets are stratified.
If the data set has train and test partitions already, they are overwritten.
