Bounds for the distance between the distributions of sums of absolutely continuous i.i.d. convex-ordered random variables with applications
Christofides, Tasos C.; Vaggelatou, E. (2009)Let X 1, X 2, ... and Y 1, Y 2,... be two sequences of absolutely continuous, independent and identically distributed (i.i.d.) random variables with equal means E(X i) = E(Y i), i = 1, 2,.... In this work we provide upper ...

A connection between supermodular ordering and positive/negative association
Christofides, Tasos C.; Vaggelatou, E. (2004)In this paper, we show that a vector of positively/negatively associated random variables is larger/smaller than the vector of their independent duplicates with respect to the supermodular order. In that way, we solve an ...
