This report enables you to specify the allocations for the training, validation, and test sets. In the boxes next to Training Set, Validation Set, and Test Set, enter values that represent the proportions or numbers of rows that you would like to include in each of these sets. The default values construct a training set that contains about 75% of the rows and a validation set that contains about 25% of the rows.

Depending on the number of rows in the data table and the selected validation method, the actual sizes of the resulting sets might vary slightly from the sizes that you specified. The Adjusted Rates, Row Counts, and Group Count columns provide the actual sizes of the sets.
