Robust covariance measure

Description

Compute robust estimates of the covariance between two variables using the robust tau estimate of univariate scale, as proposed by Maronna and Zamar (2002).

Usage

covrob(t, u)

Arguments

t

a numeric vector containing the data for the fisrt variable.

u

a numeric vector containing the data for the second variable.

Details

This function uses the scaleTau2 function from the robustbase package.

Value

Value of the robust covariance.
