Remarks
Partitioning is random and data dependent. To ensure that a particular partition can be repeated, you must specify a seed.
Notes: * To enable creation of a testing data set, the CacheMode property of the mining structure must be set to the default value, KeepTrainingCases. * Analysis Services does not support creation of holdout partitions on a mining structure. You cannot use HoldoutSeed with a mining structure that is stored in an instance of Analysis Services.
