Möbius-Invariant Goodness-of-Fit Tests for the Spherical Cauchy Model
Diego Bolón, Davy Paindaveine
We introduce a class of goodness-of-fit tests for the spherical Cauchy model on the unit hypersphere. The proposed procedures exploit the invariance of the spherical Cauchy family…

Stopping on the last success with unknown odds: asymptotic minimax optimality of the plug-in rule
Davy Paindaveine
We study the last-success problem for sequential Bernoulli trials in the homogeneous setting where are i.i.d. but the success probability $…

Win rates at first-passage times for biased simple random walks
F. Thomas Bruss, Davy Paindaveine
We study the win rate of a biased simple random walk on at the first-passage time , with . Using g…

On the robustness of semi-discrete optimal transport
Davy Paindaveine, Riccardo Passeggeri
We derive the breakdown point for solutions of semi-discrete optimal transport problems, which characterizes the robustness of the multivariate quantiles based on optimal transport…
