restimate-methods {rrcov}R Documentation

Methods for Function estimate in Package 'rrcov'

Description

Each concrete control class, like CovControlMest, CovControlOgk, etc., should implement an restimate method which will call the correponding (constructor)-function and will return the obtained S4 class, derived from CovRobust.

Usage

## S4 method for signature 'CovControlMest':
restimate(obj, x) 

Arguments

obj an object of class "CovControlEstimate"
x Data frame or matrix containing the data
... other parameters to be passed through to the estimation function.

Methods

obj = "CovControlMcd"
Compute the MCD estimates of multivariate location and scatter by callingCovMcd
obj = "CovControlMest"
Compute the constrained M-estimates of multivariate location and scatter by callingCovMest
obj = "CovControlOgk"
Compute the Ortogonalized Gnanadesikan-Kettenring (OGK) estimates of multivariate location and scatter by callingCovOgk
