Weight

public Weight()

Default construction which uses the Tricube weight.

Method Detail

setAlgorithm

public void setAlgorithm(AbstractWeightAlgorithm x)

getAlgorithm

public AbstractWeightAlgorithm getAlgorithm()

useTrueDensity

public void useTrueDensity(boolean x)

Description copied from interface: WeightAlgorithm

Set the normalizing behavior of the weight calculation.

Specified by:

useTrueDensity in interface WeightAlgorithm

isTrueDensity

public boolean isTrueDensity()

Description copied from interface: WeightAlgorithm

Returns true if the weights are being calculated under a true density. By true density we mean a kernel that integrates to 1 over its support.

Specified by:

isTrueDensity in interface WeightAlgorithm

getWeight

public DblMatrix getWeight(DblMatrix D)

Description copied from interface: WeightAlgorithm

Get the weight of a particular value.
