getFiRisk: Generic Function for Computation of Finite-Sample Risks

Description

Generic function for the computation of finite-sample risks. This function is rarely called directly. It is used by other functions.

Usage

getFiRisk(risk, Distr, neighbor, ...)
# S4 method for fiUnOvShoot,Norm,ContNeighborhood
getFiRisk(risk, Distr, neighbor, 
            clip, stand, sampleSize, Algo, cont)
# S4 method for fiUnOvShoot,Norm,TotalVarNeighborhood
getFiRisk(risk, Distr, neighbor, 
            clip, stand, sampleSize, Algo, cont)

Arguments

risk

object of class "RiskType".

Distr

object of class "Distribution".

neighbor

object of class "Neighborhood".

…

additional parameters.

clip

positive real: clipping bound

stand

standardizing constant/matrix.

sampleSize

integer: sample size.

Algo

"A" or "B".

cont

"left" or "right".

Value

The finite-sample risk is computed.

Methods

risk = "fiUnOvShoot", Distr = "Norm", neighbor = "ContNeighborhood": computes finite-sample under-/overshoot risk in methods for function getFixRobIC.
risk = "fiUnOvShoot", Distr = "Norm", neighbor = "TotalVarNeighborhood": computes finite-sample under-/overshoot risk in methods for function getFixRobIC.

Details

The computation of the finite-sample under-/overshoot risk is based on FFT. For more details we refer to Section 11.3 of Kohl (2005).
