Aggregation of Statistical Evidence under Exchangeability
Antonin Schrab, Rajen Shah, Arthur Gretton +1
We study aggregation of statistical evidence under unknown and potentially complex dependence using group-invariance. Building on permutation-based constructions that treat transfo…

More Permutations Do Not Always Increase Power: Non-monotonicity in Monte Carlo Permutation Tests
Suman Cha, Seongchan Lee, Antonin Schrab +1
Monte Carlo permutation tests are a cornerstone of valid, model-free statistical inference. A widely held practical intuition is that increasing the number of sampled permutations…

Regularized -Divergence Kernel Tests
Mónica Ribero, Antonin Schrab, Arthur Gretton
We propose a framework to construct practical kernel-based two-sample tests from the family of -divergences. The test statistic is computed from the witness function of a regula…
