Compute the error between empirical and theoretical variance of covariance matrix elements

Description

Compute the error between empirical and theoretical variance of covariance matrix elements

Usage

var_sq_err(nu, p, var_ij, xbar_ij, xbar_ii, xbar_jj)

Arguments

nu	Inverse Wishart degrees of freedom parameter
p	Matrix dimension for IW distribution
var_ij	Empirical between-subject variance of covariance matrices at element (i,j)
xbar_ij	Empirical mean of covariance matrices at element (i,j)
xbar_ii	Empirical mean of covariance matrices at the ith diagonal element
xbar_jj	Empirical mean of covariance matrices at the jth diagonal element

Value

Squared difference between the empirical and theoretical IW variance of covariance matrices at element (i,j)
