Statistica Neerlandica, Volume 79, Issue 3, August 2025.
ABSTRACT This article proposes three new goodness‐of‐fit tests for the zero‐altered Poisson distribution, or equivalently for the positive Poisson distribution, based on positive data, that is, data truncated at 0, whose test statistic is built using a characterization of this law.

Mechanical Hamiltonization of Unreduced ϕ$\phi$‐Simple Chaplygin Systems

Studies in Applied Mathematics, Volume 154, Issue 5, May 2025.
ABSTRACT In this paper, we prove that the trajectories of unreduced ϕ$\phi$‐simple Chaplygin kinetic systems are reparameterizations of horizontal geodesics with respect to a modified Riemannian metric. Furthermore, our proof is constructive and these Riemannian metrics, which are not unique, are obtained explicitly in interesting examples.
