reach.kppm: Range of Interaction for a Cox or Cluster Point Process Model

Description

Returns the range of interaction for a Cox or cluster point process model.

Usage

# S3 method for kppm
reach(x, …, epsilon)

Arguments

x

Fitted point process model of class "kppm".

epsilon

Optional numerical value. Differences smaller than epsilon are treated as zero.

…

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

Value

Numeric

Details

The range of interaction for a fitted point process model of class "kppm" 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. The argument epsilon specifies the tolerance; there is a sensible default.

Examples

# NOT RUN {
  fit <- kppm(redwood ~ 1)
  reach(fit)
# }
