estimate_pcf_fast

Fast estimation of the pair correlation function

Usage

estimate_pcf_fast(pattern, ...)

Arguments

pattern: ppp object with point pattern.
...: Arguments passed down to link{Kest} or pcf.fv.

Value

fv.object

Details

The functions estimates the pair correlation functions based on an estimation of Ripley's K-function. This makes it computationally faster than estimating the pair correlation function directly. It is a wrapper around Kest and pcf.fv.
