RPbernoulli: Simulation of Binary Random Fields

Description

Indicator or binary field which has the value 1, if an underfield field exceeds a given threshold, 0 otherwise.

Usage

RPbernoulli(phi, stationary_only, threshold)

Arguments

phi
the RMmodel. Either a model for a process or a covariance model must be specified. In the latter case, a Gaussian process RPgauss is tacitely assumed.
stationary_only
optional arguments; same meaning as for RPgauss. It is ignored if the submodel is a process definition.
threshold
real valued. RPbernoulli returns $1$ if value of the random field given by phi is equal to or larger than the value of threshold, and $0$ otherwise. In the multivariate case, a vector might be given. If the threshold is not finite, then the original field is returned. threshold defaults value is 0.

Value

The function returns an object of class RMmodel

Details

RPbernoulli can applied to any field. If only a covariance model is given, a Gaussian field is simulated as underlying field.

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

x <- seq(0, 10, 0.1)
model <- RPbernoulli(RMexp(), threshold=0)
z <- RFsimulate(model, x, x, n=4)
plot(z)
