摘要:

用截尾等方法研究独立同分布(i.i.d.)随机变量序列部分和之和的完全收敛性, 得到了与i.i.d.随机变量序列部分和完全收敛性相同的等价条件, 补充了部分和
之和的极限定理.

关键词: 独立同分布(i.i.d.); 部分和之和; 完全收敛性

Abstract:

The authors used the  cuttingofftail method and some other methods to study the complete convergence property for the sum of partial
sums of  i.i.d.random variables sequences and obtained the same equivalent conditions as those of complete convergence property of the partial sums of i.i.d. random variable sequences. The results supplement the limit theorems of the sum of partial sums.

Key words: independent identical distribution (i.i.d.); the sum of partial sums; complete convergence property
