利用截尾法和NA随机变量列的性质讨论了关于随机加权和Sn=∑j=1^nWjxj的3种不同形式的完全收敛性,得到了同分布NA列随机加权和完全收敛的若干充分条件.
By the trucated method and the properties of NA sequence,the complete convergence for randomly weighted sums Sn=∑j=1^nWjXj is discussed.Finally,several sufficient conditions for the complete convergence of randomly weighted sums are obtained.
