estimate_pcf_fast: estimate_pcf_fast

Description

Fast estimation of the pair correlation function

Usage

estimate_pcf_fast(pattern, ...)

Arguments

pattern

Point pattern.

...

Arguments passed down to `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`.
