Minimax and adaptive tests for detecting abrupt and possibly transitory changes in a Poisson process
Magalie Fromont, Fabrice Grela, Ronan Le Guével
Motivated by applications in cybersecurity and epidemiology, we consider the problem of detecting an abrupt change in the intensity of a Poisson process, characterised by a jump (n…
Optimal Change-Point Detection and Localization
Nicolas Verzelen, Magalie Fromont, Matthieu Lerasle +1
Given a times series in , with a piece-wise contant mean and independent components, the twin problems of change-point detection and change-point localizati…
A Distribution Free Unitary Events Method based on Delayed Coincidence Count
Mélisande Albert, Yann Bouret, Magalie Fromont +1
We investigate several distribution free dependence detection procedures, mainly based on bootstrap principles and their approximation properties. Thanks to this study, we introduc…
Bootstrap and permutation tests of independence for point processes
Mélisande Albert, Yann Bouret, Magalie Fromont +1
Motivated by a neuroscience question about synchrony detection in spike train analysis, we deal with the independence testing problem for point processes. We introduce non-parametr…
The two-sample problem for Poisson processes: adaptive tests with a non-asymptotic wild bootstrap approach
Magalie Fromont, Béatrice Laurent, Patricia Reynaud-Bouret
Considering two independent Poisson processes, we address the question of testing equality of their respective intensities. We first propose single tests whose test statistics are…
Adaptive tests of homogeneity for a Poisson process
M. Fromont, B. Laurent, P. Reynaud-Bouret
We propose to test the homogeneity of a Poisson process observed on a finite interval. In this framework, we first provide lower bounds for the uniform separation rates in $\mathbb…
