摘要
过原点回归直线方程y=b_0x的拟合效果可以用拟合度f表示,而y=b_0x与最优回归直线方程y=a+bx的拟合差异则可以用它们的斜率比S_r表示。
The effectiveness of a linear regression equation through origin y = o0x can be indicated by the goodness-of-fit f. In addition, the difference between y=b0x and regression equation y = a + bx, can be indicated by their slope ratio Sr.
