Inhomogeneous K- And Pair Correlation Functions Using Global Estimators

Description

Second-order summary statistics K- and pair-correlation functions describe interactions in point pattern data. This package provides computations to estimate those statistics on inhomogeneous point processes, using the methods of in T Shaw, J Møller, R Waagepetersen, 2020 <doi:10.48550/arXiv.2004.00527>.

This package accompanies Shaw et al (2020). It provides “global” estimators for the non-parametric K- and pair correlation functions, which summarize the second order interactions of second-order intensity-reweighted stationary (SOIRS) point processes. These estimators provide an alternative to those proposed by Baddeley et al (2000) for SOIRS point processes, which we refer to as “local” estimators. The local estimators are implemented in the spatstat.explore package as pcfinhom and Kinhom, with pcfcross.inhom and Kcross.inhom for the corresponding cross-pcf and cross-K-function.

Where possible, the interfaces are made to match those used by the spatstat.explore package.
