利用END变量的Rosenthal型矩不等式,研究了END随机阵列加权和的完全收敛性,给出了证明完全收敛性的一些充分条件.另外,还给出了证明完全收敛性的一个必要条件.所得结果推广了独立变量和若干相依变量的相应结果.
In this article, the complete convergence for weighted sums of arrays of rowwise extended negatively dependent random variables is obtained by using the Rosenthal type moment inequality. Some sufficient conditions to prove the complete convergence are provided. In addition, a necessary condition to prove the complete convergence is presented. The results obtained in the paper extended some corresponding ones for independent sequences and some dependent sequences.
