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.
Notes
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.
[!REMARQUE]
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.
