[System.ComponentModel.Browsable(false)]
public long HoldoutActualSize { get; set; }
[<System.ComponentModel.Browsable(false)>]
member this.HoldoutActualSize : int64 with get, set
Public Property HoldoutActualSize As Long

Property Value

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.

Attributes

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.
