最小一乘法与最小二乘法直线回归方程的比较罗文海，高永，郝恩柱求一元直线回归方程（简称回归方程）常用最小二乘法（简称二乘法）和最小一乘法（简称一乘法），对两方法的优缺点分别讨论。１．二乘法回归方程的优缺点：二乘法回归方程的基本思想是使各实测点偏离回归直...
The comparison between linear regression equations of least-squares and least-squares methods Luo Wenhai, Gao Yong, Hao Enzhu The linear regression equations for one dollar (abbreviated as regression equations) are commonly used least squares method (abbreviated as square method) and least squares method (abbreviated as a multiplication method). The advantages and disadvantages of the methods are discussed separately. 1. The advantages and disadvantages of the two-multiplication regression equation: The basic idea of the two-multiplication regression equation is to make the actual measurement points deviate from the straightforward...
