| 摘 要： | 采用分析与图解相结合的方法解决多因子非线性相关计算,求回归方程问题。先从多个因子中找出对倚变量影响最大的一个因子,作单相关曲线,求残差;再从余下的因子中找出对残差影响最大的因子,作相关曲线,求残差,直到剩余各因子对残差影响相当;最后用剩余因子线性分解残差,从而求得多因子非线性回归方程。

| Abstract: | Analysis associated with plotting methods to search for the regression equation of the correlated multi-factor was presented in the paper.To get the regression equation,the most important factor combined with its correlation graph solution was gradually used.By the comparison of the residual error between each observed and computed result,the correlation equation of multi-factor can be obtained. |

| Keywords: | linear correlation of the multi-factor non-linear correlation of the multi-factor regression equation |
