Generic Function for the Computation of Optimally Robust ICs

Description

Generic function for the computation of optimally robust ICs in case of robust models with fixed neighborhoods. This function is rarely called directly.

Usage

getFixRobIC(Distr, risk, neighbor, ...)

## S4 method for signature 'Norm, fiUnOvShoot,
##   UncondNeighborhood':
getFixRobIC(Distr, risk, neighbor, 
            sampleSize, upper, maxiter, tol, warn, Algo, cont)

Arguments

Distr object of class "Distribution".
risk object of class "RiskType".
neighbor object of class "Neighborhood".
... additional parameters.
sampleSize integer: sample size.
upper upper bound for the optimal clipping bound.
maxiter the maximum number of iterations.
tol the desired accuracy (convergence tolerance).
warn logical: print warnings.
Algo "A" or "B".
cont "left" or "right".

Value

The optimally robust IC is computed.

Methods

Distr = "Norm", risk = "fiUnOvShoot", neighbor = "UncondNeighborhood"
computes the optimally robust influence curve for one-dimensional normal location and finite-sample under-/overshoot risk.
