| 摘 要： | Let (X1,X2,…,Xn) and (Y1,Y2,…Yn) be real random vectors with the same marginal distributions,if (X1,X2,…,Xn)≤c(Y1,Y2,…Yn), it is showed in this paper that ∑i=1^n Xi≤cx∑i=1^n Yi and max1≤k≤n∑i=1^k Xi≤icx max1≤k≤n∑i=1^k Yi hold. Based on this fact,a more general comparison theorem is obtained.

| Abstract: | Let (X1,X2,…,Xn) and (Y1,Y2,…,Yn) be real random vectors with the same marginal distributions, if (X1,X2,…,Xn)≤ c (Y1,Y2,…,Yn, it is showed in this paper that Σ i=1 n X i≤ cx Σ i=1 n Yi and max1≤k≤n Σ i=1 k X i≤ icx max 1≤k≤n Σ i=1 k Yi hold. Based on this fact, a more general comparison theorem is obtained. Supported Partly by the National Natural Science Foundation of China (10371109). |
