HoldoutMaxPercent Element

Specifies the maximum percentage of cases in the data source that will be used for the holdout partition that contains the test set of a MiningStructure element. The remaining cases are used for training. A value of 0 indicates that there is no limit to the number of cases that can be held out as the test set.

Syntax

  
<MiningStructure>  
   ...  
   <ddl100_100:HoldoutMaxPercent>...</ddl100_100:HoldoutMaxPercent>  
   ...  
</MiningStructure>

Element Characteristics

Characteristic Description
Data type and length Integer between 0 and 99.
Default value 30
Cardinality 0-1: Optional element that can occur one time and one time only.

Element Relationships

Relationship Element
Parent element MiningStructure
Child elements None

Remarks

If you specify values for both HoldoutMaxPercent and HoldoutMaxCases, the algorithm limits the test set to the smaller of the two values.

If HoldoutMaxCases is set to the default of 0, and a value has not been set for HoldoutMaxPercent, the algorithm uses the complete data set for training.

The new properties HoldoutMaxCases, HoldoutMaxPercent, HoldoutSeed, or HoldoutActualSize are available only in [!INCLUDEssKatmai] and later versions. Therefore, you must prefix these properties by using the new namespace as shown in the syntax description, or [!INCLUDEssASnoversion] will return an error.

Note

In [!INCLUDEssVersion2005], [!INCLUDEssASnoversion] did not support the use of holdout partitions on a mining structure. Therefore, [!INCLUDEssASnoversion] Scripting Language (ASSL) statements that contain one of the holdout parameters, HoldoutMaxCases, HoldoutMaxPercent, HoldoutSeed, or HoldoutActualSize, cannot be used in [!INCLUDEssVersion2005]. If you use one of these holdout parameters in an ASSL statement in [!INCLUDEssVersion2005], [!INCLUDEssASnoversion] will return an error.

The element that corresponds to the parent of HoldoutMaxPercent in the Analysis Management Objects (AMO) object model is xref:Microsoft.AnalysisServices.MiningStructure.
