Comentários

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.

ObservaçãoObservação

SQL Server 2005 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 SQL Server 2005 Analysis Services.
