RMqexp: Variant of the exponential model
In RandomFields: Simulation and Analysis of Random Fields

Description Usage Arguments Value References See Also Examples

The covariance function is

C(x)= ( 2 e^{-x} - α e^{-2x} ) / ( 2 - α )

1	RMqexp(alpha, var, scale, Aniso, proj)

`alpha`	value in [0,1]
`var,scale,Aniso,proj`	optional arguments; same meaning for any `RMmodel`. If not passed, the above covariance function remains unmodified.

RMqexp returns an object of class RMmodel.

RMmodel.

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

model <- RMqexp(alpha=0.95, scale=0.2)
x <- seq(0, 10, 0.02)
plot(model)
plot(RFsimulate(model, x=x))
