All Implemented Interfaces:

Destroyable, GlobalInfoSupporter, LoggingLevelHandler, LoggingSupporter, OptionHandler, QuickInfoSupporter, SizeOfHandler, Serializable

public class RemoveWorstStdDev
extends AbstractNumericClassPostProcessor

Removes the worst predictions, which are considered outliers that detract from the actual model performance. Uses a standard deviation based approach (threshold: mean + multiplier*stdev). Only works on numeric predictions.
