摘要
定义了回归方程的拟合程度.对非线性回归方程,要化为线性方程,用相关系数、显著性水平、残余标准差率来检查回归方程和拟合程度.
The present thesis makes an effort to present a definition tothd regression level of the regression equation.It is proposed that to testify the regression equation and the regression level,non-linear equation should be converted into linear equation and also that related coefficient,manifestation level and remaining standard difference rate should all be exploited for the same purpose.
