DoubleFairWeightingFunctionGetWeights Method

Computes the fair weights for the residuals using the formula: w(r) = 1 / (1 + |r|). Here r is the adjusted redisuals from the AdjustedResidual function of the base class DoubleLeastSqWeightingFunction.

Copy

public override void GetWeights(
	DoubleVector residuals,
	ref DoubleVector weights
)

Public Overrides Sub GetWeights ( 
	residuals As DoubleVector,
	ByRef weights As DoubleVector
)

public:
virtual void GetWeights(
	DoubleVector^ residuals, 
	DoubleVector^% weights
) override

abstract GetWeights : 
        residuals : DoubleVector * 
        weights : DoubleVector byref -> unit 
override GetWeights : 
        residuals : DoubleVector * 
        weights : DoubleVector byref -> unit

Parameters

residuals DoubleVector: Residuals from the previous iteration in an iteratively Reweighted least squares problem.
weights DoubleVector: The weights. Note if the input weights vector is non-null and has the same length as the input residual vector its contents are overwritten by the new weights. Otherwise a new vector containing the weights is returned.
