基于Matlab的最小一乘回归的线性规划实现
Realization of Least-Absolute Regression Using Linear Programming Based on Matlab
【摘要】 对基于最小二乘准则的回归方法进行了分析,指出该方法容易受到野点信号的干扰.最小一乘准则虽然克服了最小二乘准则的不足,但如何在其基础上建立与实现回归算法一直是一个难题.论文中提出利用线性规划的方法建立该算法,并采用Matlab语言予以实现.
【Abstract】 The regression method based on least-square criteria is analyzed which is easy to be disturbed by noise data.The least-absolute criteria can overcome the drawbacks of least-square criteria,but how to design and implement a regression algorithm based on it is a difficult problem.In this paper,a least-absolute regression algorithm using linear programming is proposed and realized by matlab.
