Remarks

This value is dependent on source data and on the values specified for HoldoutMaxCases, HoldoutMaxPercent, and HoldoutSeed. This value is updated after processing; therefore, if you make any changes in the source data or the holdout specification, you must also reprocess the mining structure.

Note: Analysis Services does not support creation of holdout partitions on a mining structure. You cannot get or set a value for HoldoutActualSize on a mining structure that is stored in an instance of Analysis Services.
