本文研究了行为NOD随机变量阵列加权和的完全收敛性.运用NOD随机变量列的矩不等式以及截尾的方法,得到了关于行为NOD随机变量阵列加权和的完全收敛性的充分条件.利用获得的充分条件,推广了Baek(2008)关于行为NA随机变量阵列加权和的完全收敛性的结论,得到了比吴群英(2012)更为一般的结果.
In this article,the complete convergence theorem for weighted sums for arrays of rowwise NOD random variables is investigated.By using moment inequality of negatively dependent random variables and truncation method,the sufficient conditions for complete convergence of weighted sums for arrays of NOD random variables are obtained.Using the sufficient conditions,we can promote the Bake's(2008) conclusion on complete convergence of weighted sums for arrays of NOD random variables,and we can get more general results than Wu(2012).
