V2 {calibrator} | R Documentation |
distance between observation points
V2(x, other = NULL, phi)
x |
Matrix whose rows are observation points |
other |
Second matrix; if NULL , use x |
phi |
Hyperparameters |
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()
.
