reach.dppm {spatstat.model}

Range of Interaction for a Determinantal Point Process Model

Description

Returns the range of interaction for a determinantal point process model.

Usage

  ## S3 method for class 'dppm'
reach(x, ...)

  ## S3 method for class 'detpointprocfamily'
reach(x, ...)

Arguments

x

Model of class "detpointprocfamily" or "dppm".

...

Additional arguments passed to the range function of the given model.

Details

The range of interaction for a determinantal point process model may defined as the smallest number R such that g(r)=1 for all r\ge R, where g is the pair correlation function. For many models the range is infinite, but one may instead use a value where the pair correlation function is sufficiently close to 1. For example in the Matern model this defaults to finding R such that g(R)=0.99.
