getFixRobIC: Generic Function for the Computation of Optimally Robust ICs

In ROptEstOld: Optimally Robust Estimation - Old Version

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.
