RMnatsc: Natural scale

Description

RMnatsc is a stationary isotropic covariance model that depends on a stationary isotropic covariance model $phi$. The covariance is given by $$ C(h) = \phi(h / s) $$, where the argument s is chosen by RMnatsc such that the practical range or the mathematical range, if finite) is 1.

Usage

RMnatsc(phi, var, scale, Aniso, proj)

Arguments

phi
a stationary isotropic covariance RMmodel.
var,scale,Aniso,proj
optional arguments; same meaning for any RMmodel. If not passed, the above covariance function remains unmodified.

Value

RMnatsc returns an object of class RMmodel

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

model <- RMnatsc(RMexp())
x <- seq(0, 10, 0.02)
plot(RMexp(), model=model)
RFcov(model, 1)
