Property Value

Type: System.Int64
An integer that indicates the number of cases in the partition used as testing data. 0 indicates that no test partition exists, or that the structure as not been processed.

Remarks

This value is dependent on source data and on the values specified for [P:Microsoft.AnalysisServices.MiningStructure.P:Microsoft.AnalysisServices.MiningStructure.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.
