In bentaylor1/spatsurv: Bayesian Spatial Survival Analysis with Parametric Proportional Hazards Models

Description

A function to set up the computational grid and precision matrix structure for SPDE models.

Usage

setupPrecMatStruct(shape, cellwidth, no)

Arguments

shape	an object of class SpatialPolygons or SpatialPolygonsDataFrame
cellwidth	a scalar, the width of the grid cells
no	the order of the SPDE approximation: see Lindgren et al 2011 for details

Value

the computational grid and a function for constructing the precision matrix
