A conditional machine learning classification approach for spatio-temporal risk assessment of crime data
Rodrigues, Alexandre; González, Jonatan A.; Mateu, Jorge Springer (2023)Crime data analysis is an essential source of information to aid social and political decisions makers regarding the allocation of public security resources. Computer-aided dispatch systems and technological advances in ... -
Analysis of tornado reports through replicated spatiotemporal point patterns
González, Jonatan A.; Hahn, Ute; Mateu, Jorge Wiley (2019-09)Understanding the spatiotemporal distribution of tornado events is increasingly imperative, not only because of the natural phenomenon itself and its tremendous complexity but also because we can potentially reduce the ... -
Classification of Events Using Local Pair Correlation Functions for Spatial Point Patterns
González, Jonatan A.; Rodríguez-Cortés, Francisco Javier; Romano, Elvira; Mateu, Jorge American Statistical Association (2021-05-12)Spatial point pattern analysis usually concerns identifying features in an observation window where there is also noise. This identification traditionally begins with studying the second-order properties of the point ... -
Graphical modelling and partial characteristics for multitype and multivariate-marked spatio-temporal point processes
Eckardt, Matthias; González, Jonatan A.; Mateu, Jorge Elsevier (2021-04)A method for dealing with multivariate analysis of marked spatio-temporal point processes is presented by introducing different partial point characteristics, and by extending the spatial dependence graph model formalism. ... -
Nonparametric testing of the dependence structure among points-marks-covariates in spatial point patterns
Mateu, Jorge; Mrkvicka, Tomas; Dvořák, Jiří; González, Jonatan A. John Wiley & Sons (2022-05-16)We investigate testing of the hypothesis of independence between a covariate and the marks in amarked point process. It would be rather straightforward if the (unmarked) point process wereindependent of the covariate and ... -
Revisiting the random shift approach for testing in spatial statistics
Mrkvicka, Tomas; Dvořák, Jiří; González, Jonatan A.; Mateu, Jorge Elsevier (2020)We consider the problem of non-parametric testing of independence of two components of a stationary bivariate spatial process. In particular, we revisit the random shift approach that has become the standard method for ... -
Two-way layout factorial experiments of spatial point pattern responses in mineral flotation
González, Jonatan A.; Lagos Álvarez, Bernardo M.; Mateu, Jorge Springer (2021-03-25)Factorial experiments are well-understood when the given observations are outcomes of random variables. However, when we observe spatial point patterns in each combination of factors cells, the methodology is much less ...
