负相关NA( negatively associated)随机变量序列是一类较弱的相依序列。讨论了NA随机变量序列的Berry-Esseen界问题,在不同的条件下,得到了Berry-Esseen界分别为O ( n-1/4· log n · log log n)和 O ( n-1/6· log n · log log n),结果推广了已有文献的相关结论。
The negatively associated( NA) sequence of random variables is a weak dependent sequence. The Berry-Es-sen bound for the sequence of negatively associated random variables was discussed. Under some diffident conditions, the Berry-Esseen bounds were respectively presented as O(n-1/4·logn·loglogn) and O(n-1/6·logn·loglogn), and the results extend the corresponding one in the literature.
