# HoldoutMaxCases Element
  Specifies the maximum number of cases in the data source to be used for the holdout partition that contains the test set of a [MiningStructure](../../../analysis-services/scripting/objects/miningstructure-element-assl.md) element. The remaining cases in the data set 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  
  
```xml  
  
<MiningStructure>  
   ...  
   <ddl100_100:HoldoutMaxCases>...</ddl100_100:HoldoutMaxCases>  
   ...  
</MiningStructure>  
```  
  
## Element Characteristics  
  
|Characteristic|Description|  
|--------------------|-----------------|  
|Data type and length|Integer greater than 0.|  
|Default value|0|  
|Cardinality|0-1: Optional element that can occur one time and one time only.|  
  
## Element Relationships  
  
|Relationship|Element|  
|------------------|-------------|  
|Parent element|[MiningStructure](../../../analysis-services/scripting/objects/miningstructure-element-assl.md)|  
|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 entire data set for training.  
  
 The new properties **HoldoutMaxCases**, **HoldoutMaxPercent**, **HoldoutSeed**, or **HoldoutActualSize** are available only in [!INCLUDE[ssKatmai](../../../includes/sskatmai-md.md)] and later versions. Therefore, you must prefix these properties with the new namespace as shown in the syntax description, or [!INCLUDE[ssASnoversion](../../../includes/ssasnoversion-md.md)] will return an error.  
  
> [!NOTE]  
>  In [!INCLUDE[ssVersion2005](../../../includes/ssversion2005-md.md)], [!INCLUDE[ssASnoversion](../../../includes/ssasnoversion-md.md)] did not support the use of holdout partitions on a mining structure. Therefore, [!INCLUDE[ssASnoversion](../../../includes/ssasnoversion-md.md)] Scripting Language (ASSL) statements that contain one of the holdout parameters, **HoldoutMaxCases**, **HoldoutMaxPercent**, **HoldoutSeed**, or **HoldoutActualSize**, cannot be used in [!INCLUDE[ssVersion2005](../../../includes/ssversion2005-md.md)]. If you use one of these holdout parameters in an ASSL statement in [!INCLUDE[ssVersion2005](../../../includes/ssversion2005-md.md)], [!INCLUDE[ssASnoversion](../../../includes/ssasnoversion-md.md)] will return an error.  
  
 The element that corresponds to the parent of **HoldoutMaxCases** in the Analysis Management Objects (AMO) object model is <xref:Microsoft.AnalysisServices.MiningStructure>.
