getFixClip {ROptEst}

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,  ...)

## S4 method for signature 'numeric,Norm,fiUnOvShoot,ContNeighborhood'
getFixClip(clip, Distr, risk, neighbor)

## S4 method for signature '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.

Methods

clip = "numeric", Distr = "Norm", risk = "fiUnOvShoot", neighbor = "ContNeighborhood"

optimal clipping bound for finite-sample under-/overshoot risk.

clip = "numeric", Distr = "Norm", risk = "fiUnOvShoot", neighbor = "TotalVarNeighborhood"

optimal clipping bound for finite-sample under-/overshoot risk.
