Method Detail

distance

public double distance(MultiTable.Block.Column x,
                       MultiTable.Block.Column y,
                       double defaultValue)

Description copied from class: QualityMeasure

Returns the distance of the two vectors x and y with the given root. This may be the root in a formal way or a default value to be returned if the distance uses a non defined operation. If one array is longer than the other one additional values do not contribute to the distance. Double.NaN values are also ignored.

Specified by:

distance in class QualityMeasure

Parameters:

x - an array

y - another array

defaultValue - The value to be returned in cases in which no distance computation is possible.

Returns:

The distance between the two arrays x and y.

distanceToZero

public double distanceToZero(MultiTable.Block.Column x,
                             double defaultValue)
