cov_control {robmed}

Tuning parameters for Huber M-estimation of location and scatter

Description

Obtain a list with tuning paramters for cov_Huber().

Usage

cov_control(prob = 0.95, max_iterations = 200, tol = 1e-07)

Arguments

prob

numeric; probability for the quantile of the \chi^{2} distribution to be used as cutoff point in the Huber weight function (defaults to 0.95).

max_iterations

an integer giving the maximum number of iterations in the iteratively reweighted algorithm.

tol

a small positive numeric value to be used to determine convergence of the iteratively reweighted algorithm.

Value

A list with components corresponding to the arguments.
