Model of class "detpointprocfamily" or "dppm".

…

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

Value

Numeric

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 \(g(R)=0.99\).

Examples

# NOT RUN {
reach(dppMatern(lambda=100, alpha=.01, nu=1, d=2))
# }
