Property Value

Type: System.Int64

An integer that contains the holdout seed. If 0, a hash of the ID of the MiningStructure is used as the seed. The default value is 0.

Remarks

Partitioning is random and data dependent. To ensure that a particular partition can be repeated, you must specify a seed.

Note   To enable creation of a testing data set, the CacheMode property of the mining structure must be set to the default value, KeepTrainingCases.

Note

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.
