Lambda2cov: Transform variogram matrix to covariance of conditional random field

Description

The matrix Lambda is half the semivariogram matrix. The function returns the conditional covariance with respect to entries in co, restricted to the subA rows and the subB columns.

Usage

Lambda2cov(Lambda, co, subA, subB)

Arguments

Lambda

Negative definite matrix for the Huesler--Reiss model

co

vector of integer with conditioning sites

subA

vector of integers with sub-entries (not in co) for rows

subB

vector of integers with sub-entries (not in co) for columns. If missing, default to subA.
