One marked-sum law determines random mass partitions and $Ξ$ -coalescents

Jacopo Lenzi

Let $P = (P_{j})$ be a random mass partition and let $(X_{j})$ be iid real marks, independent of $P$ . We construct a fixed mark distribution for which the law of the real random variable…

Dimension comparison for Student's statistic under symmetric unimodality

Jacopo Lenzi

Let $q_{n} (r)$ denote the tail probability at $r$ of the self-normalized sum of $n$ independent centered uniform variables. At $r = 3$ , the first distribution-sensitive term in the two…
