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

Description

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

Usage

getFixClip(clip, Distr, risk, neighbor, ...)

## S3 method for class 'numeric,Norm,fiUnOvShoot,ContNeighborhood':
getFixClip(clip, Distr, risk, neighbor)

## S3 method for class 'numeric,Norm,fiUnOvShoot,TotalVarNeighborhood':
getFixClip(clip, Distr, risk, neighbor)

Arguments

clip

positive real: clipping bound

Distr

object of class "Distribution".

risk

object of class "RiskType".

neighbor

object of class "Neighborhood".

...

additional parameters.

Value

• The optimal clipping bound is computed.

concept

influence curve
