Web1 aug. 2005 · We provide an optimization framework for computing optimal upper and lower bounds on functional expectations of distributions with special properties, given moment constraints. Bertsimas and Popescu (Optimal inequalities in probability theory: a convex optimization approach. WebThe hybrid ambiguity set consists of Wasserstein metric, and moment and bounded support information of random parameters. An equivalently tractable non-convex conic program is given, and relaxed and conservative approximations are derived.
