致精进的你:
同学你好,Sum of Squared Regression其实就是回归平方和,也就是我们常说的RSS;另外总结一下: 1.总平方和(Total sum of squares,TSS或Sum of squares total,SST ), 2.解释平方和或回归平方和(Explained sum of squares,ESS或Sum of explained squares,SSE或sum of squared regression,SSR,或regressor sum of squares,RSS), 3.残差平方和(sum of quared errors,SSE或sum of squared residuals,SSR)。 4.残差项的均方和(mean square error,MSE或mean square residual,MSR) 5.解释变量/回归的均方和(Explainary/regression mean square ,MSR/MSE) 不要只看缩写,重点看全称或题干
