complete_Gamma_general {graphicalExtremes}

Non-decomposable completion of variogram matrices

Description

Given a non-decomposable graph, and (non-graphical) variogram matrix Gamma, modifies Gamma in non-edge entries, such that the resulting matrix is a variogram matrix with graphical structure described by graph.

Usage

complete_Gamma_general(
  Gamma,
  graph,
  N = 10000,
  tol = get_large_tol(),
  check_tol = 100
)

Arguments

Gamma

Numeric d \times d variogram matrix.

graph

igraph::graph() object.

N

Maximum number of iterations.

tol

Numeric scalar. Tolerance to be used when completing submatrices.

check_tol

Numeric/integer scalar. How often to check the tolerance when completing submatrices.

Value

A completed d \times d variogram matrix.
