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 class 'kppm'
reach(x, ..., epsilon)
Arguments
x |
Fitted point process model of class |
epsilon |
Optional numerical value. Differences smaller than
|
... |
Additional arguments passed to the range function of the given model. |
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.
