RMgennsst: Non-Separable Space-Time model

Description

RMgennsst is a univariate stationary spaceisotropic covariance model whose corresponding covariance is given by $$C(h,u)= (\psi(u)+1)^{-\delta/2} \phi(h /\sqrt(\psi(u) +1))$$

Usage

RMgennsst(phi, psi, var, scale, Aniso, proj)

Arguments

phi
is normal mixture RMmodel, cf. RFgetModelNames(monotone="normal mixture")
psi
is a variogram RMmodel.
var,scale,Aniso,proj
optional arguments; same meaning for any RMmodel. If not passed, the above covariance function remains unmodified.

Value

Details

This model is used for space-time modelling where the spatial component is isotropic.

Examples

Run this code
RFoptions(seed=0) ## *ANY* simulation will have the random seed 0; set
##                   RFoptions(seed=NA) to make them all random again
