鲁棒回归之Least Median of Squares(LMedS) 简介 这里我们来看一个比较少见的鲁棒回归中的方法:最小中值二乘法(Least Median of Squares, LMedS),其对应的优化问题为: 为残差,为优化变量(1)argminβ S(β)=median(ri2),ri为残差,β为优化变量 它和最小二乘法不同,最小二乘法本质上就是优化均值,LMedS...

鲁棒回归之Least Median of Squares(LMedS) 这里我们来看另一个鲁棒回归中的方法:截断最小二乘法(Least Trimmed Squares, LTS),顾名思义,这个方法会把一部分残差剔除,它可以显式地剔除野值点的影响。 鲁棒回归中抛锚点概念 抛锚点 ϵ (Breakdown Point)是指样本中最高脏数据的比例,在该比例下,估计量(Estimato...

Classical least squares regression consists of minimizing the sum of the squared residuals. Many authors have produced more robust versions of this estimator by replacing the square by something else, such as the absolute value. In this article a different approach is introduced in which the sum ...

Ordinary least squares (OLS) regression is relatively sensitive to the presence of outliers in a data set. In this paper, a robust estimation method, least median of squares (LMS) is used to identify outliers in land value data. Once the outliers are identified, are the land value equations...
