V2 {calibrator}R Documentation

distance between observation points

Description

distance between observation points

Usage

V2(x, other = NULL,  phi)

Arguments

x Matrix whose rows are observation points
other Second matrix; if NULL, use x
phi Hyperparameters

Details

This function returns the variance matrix of observations of the real process z at points D2={x_1,...,x_n}.

It appears in the lower right corner of the variance matrix on the bottom of page 1 of the supplement, calculated by function Vd().

It is also used in functions Cov.eqn9.supp() and V.fun().
