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 ... WebOptimization with Marginals and Moments discusses problems at the interface of optimization and probability. Combining optimization and probability leads to computational challenges. At the same time, it allows us to model a large class of planning problems. ready 2 roof meridian ms
