locMEstimator {RobAStBase}R Documentation

Generic function for the computation of location M estimates

Description

Generic function for the computation of location M estimates.

Usage

locMEstimator(x, IC, ...)

## S4 method for signature 'numeric, InfluenceCurve':
locMEstimator(x, IC, eps = .Machine$double.eps^0.5)

Arguments

x sample
IC object of class "InfluenceCurve"
... additional parameters
eps the desired accuracy (convergence tolerance).

Details

Given some sample x and some influence curve IC an M estimate is computed by solving the corresponding M equation.

Value

Object of class "MEstimate"

Methods

x = "numeric", IC = "InfluenceCurve"
univariate location.
