摘要
人们普遍认为要从理论上通过数学分析的方法来论证不连序系列样本概率权重矩的偏倚性是很困难的。本文根据次序统计量理论，分析推证了不连序系列样本概率权重矩的不偏计算公式。论证结果具有较重要的理论和实用意义。
It is considered difficult to analytically prove whether sample probability weighted moments with discrete series are unbiased estimators.According to the theory of order statistics,the paper analytically proves the unbiased calculating formulas of sample probability weighted moments with discrete series. In a sense,it is valuable in theory and practice to have the proved results.
