In cmjt/lgcpSPDE: Fitting and Simulation for log-Gaussian Cox processes using INLA/SPDE approach

Description

Function to simulate from a spatial/spatio temporal SPDE model

Usage

rgeospde(locs = NULL, mesh = NULL, kappa = NULL, sigma2 = 1, n = 1,
  rho = 0.9, seed = 1, non.stat = NULL)

Arguments

locs	a matrix of locations at which the values are to be simulated
mesh	a “mesh” object i.e. delauney triangulation of the domain, an object returned by make.mesh.
kappa	a numeric constant, parameter of the SPDE model.
sigma2	a numeric constant, parameter of the SPDE model, by default this is 1.
n	a numeric constant defining the number of time points, by default 1.
rho	the ar1 correlation coefficient for spatio-temporal samples, by default this is 0.9.
seed	seed for the simulation, by default this is 1
non.stat	a named list the first element fn the spatial function which kappa varies with and theta a vctor of length 3 specifying the theta values of the non-stationary model

Value

A matrix of values each column a set of observations at each time point
