iid_covariance_vec {wwntests}

Compute part of the covariance under a strong white noise assumption

Description

'iid_covariance_vec' A helper function used to compute one of the two independent sum terms in the computation of the approximate covariance of the functional data under a strong white noise assumption; a vectorized version of iid_covariance.

Usage

iid_covariance_vec(f_data)

Arguments

f_data

the functional data matrix with observed functions in the columns

Value

A 2-dimensional matrix containing one of the two independent sums in the computation of the covariance.
