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 ...
在一般地线性回归模型中,有ESS+RSS=TSS(证明过程参见:Partitioning in the general ordinary least squares model) 在这种情况下:我们有R2=1−RSSTSS=ESSTSS=∑i(fi−^y)2∑i(yi−^y)2 对于R2我们需要注意: R2 Regression Analysis: How Do I Interpret R-squared and Assess the Goodness-of-Fit?
