Description Usage Arguments Value

View source: R/lgcp-INLA.R

Description

A function to compute the parametrised base matrix of a precision matrix of a GMRF on an M x N toral grid with neighbourhood size ns. Note that the precision matrix is block circulant. The returned function operates on a parameter vector as in Rue and Held (2005) pp 187.

Usage

1
paramprecbase(ns, M, N, inverse = FALSE)

Arguments

ns

neighbourhood size

M

number of x cells

N

number of y cells

inverse

whether or not to compute the base matrix of the inverse precision matrix (ie the covariance matrix). default is FALSE

Value

a functioin that returns the base matrix of the precision matrix
