Element Characteristics
| Characteristic | Description |
|---|---|
| FoldIndex | Integer that indicates the starting position of the partition that is used for cross-validation. |
| FoldCount | Integer that indicates the number of partitions in the model after cross-validation. |
| MaxCases | Integer that indicates how many model cases are used for cross-validation. A value of 0 indicates that all cases are used. |
| FoldTargetAttribute | String that indicates the ID of the model column that contains the predictable attribute. |
