| 摘 要： | 利用随机变量的截尾方法和两两PQD序列的矩不等式,得到了矩条件下两两PQD序列部分和之和的弱大数律,该结果去除了随机变量对称同分布的限制条件,推广了若干已有的弱大数律。

| Abstract: | The weak law of large numbers for sum of partial sums of pairwise PQD sequence of random variables is obtained under the moment conditions by the truncation methods of random variables and moment inequalities of pairwise PQD sequence.The available results which eliminate the restriction of symmetric random variable and identical distribution extend to some known theorems. |
