difference_fullcov {covsep}

compute the difference between the full sample covariance and its separable approximation

Description

compute the difference between the full sample covariance and its separable approximation

Usage

difference_fullcov(Data)

Arguments

Data

a (non-empty) N x d1 x d2 array of data values. The first direction indices the N observations, each consisting of a d1 x d2 discretization of the surface, so that Data[i,,] corresponds to the i-th observed surface.

Value

A d1 x d2 x d1 x d2 array, where d1 = nrow(Data) and d2 = ncol(Data).

Details

This is an internal function.
