Exploring first and second-order spatio-temporal structures of lightning strike impacts in the French Alps using subsampling
Jean-François Coeurjolly, J Blanchet, Alexis Pellerin
We model cloud-to-ground lightning strike impacts in the French Alps over the period 2011-2021 (approximately 1.4 million of events) using spatio-temporal point processes. We inves…
Regularization techniques for inhomogeneous (spatial) point processes intensity and conditional intensity estimation
Jean-François Coeurjolly, Ismaïla Ba, Achmad Choiruddin
Point processes are stochastic models generating interacting points or events in time, space, etc. Among characteristics of these models, first-order intensity and conditional inte…
Pairwise interaction function estimation of Gibbs point processes using basis expansion
Ismaïla Ba, Jean-François Coeurjolly, Francisco Cuevas-Pacheco
The class of Gibbs point processes (GPP) is a large class of spatial point processes able to model both clustered and repulsive point patterns. They are specified by their conditio…
Adaptive lasso and Dantzig selector for spatial point processes intensity estimation
Achmad Choiruddin, Jean-François Coeurjolly, Frédérique Letué
Lasso and Dantzig selector are standard procedures able to perform variable selection and estimation simultaneously. This paper is concerned with extending these procedures to spat…
Second-order variational equations for spatial point processes with a view to pair correlation function estimation
Jean-François Coeurjolly, Francisco Cuevas-Pacheco, Rasmus Waagepetersen
Second-order variational type equations for spatial point processes are established. In case of log linear parametric models for pair correlation functions, it is demonstrated that…
Spatial point processes intensity estimation with a diverging number of covariates
Achmad Choiruddin, Jean-François Coeurjolly, Frédérique Letué
Feature selection procedures for spatial point processes parametric intensity estimation have been recently developed since more and more applications involve a large number of cov…
