We establish higher-order nonasymptotic expansions for a difference between probability distributions of sums i.i.d. random vectors in Euclidean space. The derived bounds are uniform over two classes sets: the set all balls and half-spaces. These results allow to account an impact moments or cumulants considered distributions; obtained error terms depend on sample size dimension explicitly. new...

Robust optimization (RO) is a common approach to tractably obtain safeguarding solutions for problems with uncertain constraints. In this paper, we study statistical framework integrate data into RO based on learning prediction set using (combinations of) geometric shapes that are compatible established tools and simple data-splitting validation step achieves finite-sample nonparametric guarant...
