Portfolio Selection With Higher Moments

WebApr 27, 2024 · Abstract. In this paper, we study the class of linear and discrete optimization problems in which the objective coefficients are chosen randomly from a distribution, and the goal is to evaluate robust bounds on the expected optimal value as well as the marginal distribution of the optimal solution. Webfourth marginal moments exactly (instead of matching all third and fourth marginal moments approximately, as in [8]). However, the computational sim-plicity as well as stability of results demonstrated in this paper arguably out-weigh this shortcoming. If better moment-matching is needed for higher order marginals, the proposed method can ...

Webtic combinatorial optimization problems by assuming that information on nonoverlapping multivariate marginals are available. A popular tool to construct multivariate distri-butions from univariate distributions is the copula that helps distinguish the dependencies from the marginals.
