Generic Function for the Computation of the Standardizing Matrix

Description

Generic function for the computation of the standardizing matrix which takes care of the Fisher consistency of the corresponding IC. This function is rarely called directly. It is used to compute optimally robust ICs.

Usage

getInfStand(L2deriv, neighbor, ...)

## S4 method for signature 'UnivariateDistribution,
##   ContNeighborhood':
getInfStand(L2deriv, neighbor, clip, cent, trafo)

## S4 method for signature 'UnivariateDistribution,
##   TotalVarNeighborhood':
getInfStand(L2deriv, neighbor, clip, cent, trafo)

## S4 method for signature 'RealRandVariable,
##   ContNeighborhood':
getInfStand(L2deriv, neighbor, Distr, A.comp, stand, clip, cent, trafo)

Arguments

L2deriv L2-derivative of some L2-differentiable family of probability measures.
neighbor object of class "Neighborhood"
... additional parameters
clip optimal clipping bound.
cent optimal centering constant.
stand standardizing matrix.
Distr object of class "Distribution".
trafo matrix: transformation of the parameter.
A.comp matrix: indication which components of the standardizing matrix have to be computed.

Value

The standardizing matrix is computed.

Methods

L2deriv = "UnivariateDistribution", neighbor = "ContNeighborhood"
computes standardizing matrix.
L2deriv = "UnivariateDistribution", neighbor = "TotalVarNeighborhood"
computes standardizing matrix.
L2deriv = "RealRandVariable", neighbor = "ContNeighborhood"
computes standardizing matrix.
