oneStepEstimator: Generic function for the computation of one-step estimators

Description

Generic function for the computation of one-step estimators.

Usage

oneStepEstimator(x, IC, start)

Arguments

x

sample

IC

object of class "InfluenceCurve"

start

initial estimate

Value

The one-step estimation is computed.

Methods

x = "numeric", IC = "InfluenceCurve", start = "numeric"

univariate samples.

x = "numeric", IC = "InfluenceCurve", start = "list"

univariate samples.

x = "matrix", IC = "InfluenceCurve", start = "numeric"

multivariate samples.

x = "matrix", IC = "InfluenceCurve", start = "list"

multivariate samples.

Details

Given an initial estimation start, a sample x and an influence curve IC the corresponding one-step estimator is computed
