What is the Fourier Transform of a Spatial Point Process?
Tuomas A. Rajala, Sofia C. Olhede, Jake P. Grainger +1
This paper determines how to define a discretely implemented Fourier transform when analysing an observed spatial point process. To develop this transform we answer four questions;…
Multivariate Geometric Anisotropic Cox Processes
James S. Martin, David J. Murrell, Sofia C. Olhede
This paper introduces a new modelling framework for multivariate anisotropic Cox processes. Building on recent innovations in multivariate spatial statistics, we propose a new fami…
Detecting multivariate interactions in spatial point patterns with Gibbs models and variable selection
Tuomas Rajala, David Murrell, Sofia Olhede
We propose a method for detecting significant interactions in very large multivariate spatial point patterns. This methodology develops high dimensional data understanding in the p…
