属性值
类型：System.Int32
An integer between 0 and 99 that indicates the percentage of source data used for testing.
注释
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 set, 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.
Note To enable creation of a testing data set, the CacheMode property of the mining structure must be set to the default value, KeepTrainingCases.

SQL Server 2005 does not support creation of holdout partitions on a mining structure. You cannot use HoldoutMaxPercent with a mining structure that is stored in an instance of SQL Server 2005 Analysis Services. |
