Let $C$ be a bivariate copula, that is, a distribution function on $[0,1]^2$ with uniform marginals. A copula is stochastically increasing when it satisfies the stochastic increasi…

Let $X$ be a finite min-max closed configuration of points in $\mathbb{R}^d$ such that … Here, $X$ is MTP2-tidy when the set of feasible tent-function heights yielding supermodular…

Let $X$ be a sample configuration, and consider maximum likelihood estimation under the $\text{MTP}_2$ and LLC log-concavity constraints. A configuration is tidy when the correspon…
