Description

This function computes the empirical variance function as described in Said et al., 2015.

Usage

1
emp_var_function(mu, scm_list)

Arguments

mu

the geometric mean of the sample covariance matrices in scm_list. It is in fact the mean of the Riemann-Gauss distribution described in Said et al., 2015. For more details see the References below.

scm_list

a list of numeric sample covariance matrices.

Value

It returns a numeric value, that is the empirical variance function estimated.
