研究宽上限相依随机变量和的尾概率问题,利用截断误差的方法得到一个宽上限相依的随机变量和的尾概率不等式,它将负相依同分布的随机变量和的结论推广到宽上限相依不同分布的相应的形式上.

英文摘要：

The issue of the tail probability of sums of wide upper bound-dependent random variables is studied and an inequality of tail probability for sums of foregoing variables is obtained by using a standard error truncation method, making the conclusion for the sums of random variables with negative depend- ence and identical distribution generalized to a corresponding form for the variables with wide upper bound dependence and various distribution.
