摘要
自变量、因变量的不同选择,用传统的最小二乘法得到的回归方程是不同的。提出直线回归的最小面积法解决这一问题,推导了该方法的计算公式并讨论了该方法的一些性质。
Linear regression equations obtained by least square method are different if independent variable x and dependent variable y are exdanged a least area method is proposed in this paper to solved the , calculating formulae are derived and properties are discussed for this method.
