注释
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.
