基于M估计的迭代最小二乘算法，其中估计量有Huber,Andrews,Hampel,Ramsay等。-M is estimated based on the iterative least-squares algorithm, which estimates there are Huber, Andrews, Hampel, Ramsay and so on.

关于鲁棒估计的C#源程序，有三种经典方法：M估计的IGGI方案，Hampel函数做标准等价权以及Huber稳健估计-The Robust Estimation written in C# There are three classical methods: M estimates IGGI program, Hampel function equivalent weights and the standard Huber robust
