estimate_pcf_fast: estimate_pcf_fast

Description

Fast estimation of the pair correlation function

Usage

estimate_pcf_fast(pattern, ...)

Value

fv.object

Arguments

pattern

Point pattern.

...

Arguments passed down to `Kest` or `pcf.fv`.

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 and returns a 'Function value object' of the spatstat package.
