摘要
论述了用最小一乘法估计两变数线性回归模型中的参数。计算方法为：通过定点的解法，一般解法，两点法和单纯形法。对于最小一乘解，在实际分析时会出现一些问题，如解的不灵敏性、解的多重性以及突出点的多少对回归线有不同影响等。
This paper describes the least one-power method of estimating the parameters in linear regression model of two variables,which is used in the solving method by fixed point, general solving method,two points method and simplex method. For the least one-power solution, in the practical analysis,some problems may appear,such as the insensitivity of solution,multi-fold solutions and the various eftbcts of outliers amount on the regression line.
