All Implemented Interfaces:: ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class StandardDeviationWeighting
extends AbstractWeighting
extends AbstractWeighting

Creates weights from the standard deviations of all attributes. The values can be normalized by the average, the minimum, or the maximum of the attribute.

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.
