| 摘 要： | 结合使用Huber的M估计和最小距离(MD)估计,构造了一种P-Ⅲ型总体下的频率分析方法。统计试验结果表明,当样本中有一定比例干扰数据的影响时,该方法具有较好的稳健性;同时,当样本中无干扰数据的影响时,该方法亦具有相对较优的统计性能。

| Abstract: | A robust estimate method for Hydrological frequency analysis is developed by Combining Huber's M-estimate and Minimum Distance (MD) estimate in this paper.To P-Ⅲ distribution,Monte-carlo results show that the methed presented is robust when the sample is contaminated by some interference data,and simultaneously is better statistical characteristics when the sample is not contaminated by some interference data. |
