The Relationship between R-squared and R in Regression Analysis In regression analysis, R-squared (R2) and R are two important measures used to assess the goodness of fit of a regression model. Although they both provide information about the strength of the relationship between the independent ...

被解释变量 y 的方差,即总离差平方和(total sum of squares, TSS), 可以被分解为两部分,回归平方和(regression sum of squares, RSS) 以及残差平方和(error sum or squares, ESS)。 Var(y)=TSS=Var(y^)+Var(e)=RSS+ESS[2] 其中,y^为被解释变量的预测值。
