Testing the first-order separability hypothesis for spatio-temporal point patterns
Mohammad Ghorbani, Nafiseh Vafaei, Jiří Dvořák +1
First-order separability of a spatio-temporal point process plays a fundamental role in the analysis of spatio-temporal point pattern data. While it is often a convenient assumptio…
Graphical tests of independence for general distributions
Jiří Dvořák, Tomáš Mrkvička
We propose two model-free, permutation-based tests of independence between a pair of random variables. The tests can be applied to samples from any bivariate distribution: continuo…
Nonparametric testing of the dependence structure among points-marks-covariates in spatial point patterns
Jiří Dvořák, Tomáš Mrkvička, Jorge Mateu +1
We investigate testing of the hypothesis of independence between a covariate and the marks in a marked point process. It would be rather straightforward if the (unmarked) point pro…
Revisiting the random shift approach for testing in spatial statistics
Tomas Mrkvicka, Jiri Dvorak, Jonatan A. Gonzalez +1
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 t…
