| 摘 要： | 在抗差稳健估计中,选权迭代法应用最广,较易理解,M估计法计算简单。基于M估计的基本理论,深入分析Huber、Hampel、IGG3种常用的选权迭代法,并利用水准网数据,分析这3种常用选权迭代法的适用范围和相应的抗差效果,表明IGG法比其他两种的抗粗差效果要好,且易实现。

| Abstract: | In the robust estimation,selecting weight iteration method is the most widely understood,more easily and simple calculation of M estimation.Based on the basic theory of M estimation method,this paper deeply analyzes three common selecting weight iteration methods which are Huber、Hampel、IGG methods,and analyzes the applicable scope and corresponding poor effect on the three commonly selecting weight iteration methods by using the data of the network level.It shows that the excorresponding poor effect of the ... |
