Specifies a number to use to seed the pseudo-random generator when randomly determining the holdout data for this algorithm. If HOLDOUT_SEED is set to 0, the algorithm generates the seed based on the name of the mining model, to guarantee that the model content remains the same during reprocessing.   This value is unique to this algorithm and is unrelated to any holdout parameters set in the mining structure.   The default is 0.
