摘要
最小二乘法在有异常点存在时,其回归方程的"稳健性"往往受到影响。本文利用中位数比平均数稳健这一性质,给出一种可抗异常点干扰的一元稳健回归方程的求解方法。
The least square method can easily be influenced so that equations based on it are unrobust when there are some out- liers.In this paper,by using of the property of medians more robust than averages,a new method of first order robust re- gressive equation was proposed,which resists effectively resist against outliers.
