Property Value
An integer that indicates the maximum number of cases in the training data set. A value of 0 indicates no limit.
Remarks
If values are set for both HoldoutMaxCases and HoldoutMaxPercent, the lower limit is used. If no value is set for HoldoutMaxPercent and the value for HoldoutMaxCases is 0, all the data is used for testing and none for training.
If the size of the final testing data, based on all holdout parameters, equals or exceeds the total number of cases, a warning is raised. An error is also raised if the testing set is bigger than the training set.
Uwaga
To enable creation of a testing data set, the CacheMode property of the mining structure must be set to the default value, KeepTrainingCases.
Uwaga
SQL Server 2005 does not support creation of holdout partitions on a mining structure. You cannot use HoldoutMaxCases with a mining structure that is stored in an instance of SQL Server 2005 Analysis Services.
