getInfClipRegTS: Generic Function for the Computation of the Optimal Clipping Bound

Description

Generic function for the computation of the optimal clipping bound/function. This function is rarely called directly. It is used to compute optimally robust ICs in case infinitesimal models.

Usage

getInfClipRegTS(clip, ErrorL2deriv, Regressor, risk, neighbor, ...)

# S4 method for numeric,UnivariateDistribution,Distribution,asMSE,Neighborhood getInfClipRegTS( clip, ErrorL2deriv, Regressor, risk, neighbor, z.comp, stand, cent)

# S4 method for numeric,UnivariateDistribution,Distribution,asMSE,Av1CondTotalVarNeighborhood getInfClipRegTS( clip, ErrorL2deriv, Regressor, risk, neighbor, z.comp, stand, cent)

# S4 method for numeric,EuclRandVariable,Distribution,asMSE,Neighborhood getInfClipRegTS( clip, ErrorL2deriv, Regressor, risk, neighbor, ErrorDistr, stand, cent, trafo)

# S4 method for numeric,UnivariateDistribution,UnivariateDistribution,asUnOvShoot,UncondNeighborhood getInfClipRegTS( clip, ErrorL2deriv, Regressor, risk, neighbor, z.comp, cent)

# S4 method for numeric,UnivariateDistribution,numeric,asUnOvShoot,CondNeighborhood getInfClipRegTS( clip, ErrorL2deriv, Regressor, risk, neighbor)

Arguments

clip

optimal clipping bound.

ErrorL2deriv

L2-derivative of ErrorDistr.

standardizing matrix.

z.comp

which components of the centering constant/function have to be computed.

ErrorDistr

error distribution.

trafo

matrix: transformation of the parameter.

Value

The optimal clipping bound/function is computed.
