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, loggauss, 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

loggauss, stationary_only

optional parameters; same meaning as for RPgauss. They will be 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. threshold

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.
