Non-Separable Space-Time model

Description

RMgennsst is a univariate stationary spaceisotropic covariance model whose corresponding covariance is given by

C(h,u)= (ψ(u)+1)^{-δ/2} φ(h /√(ψ(u) +1))

Usage

1
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.

Details

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

Value

RMgennsst returns an object of class RMmodel.
