WebSep 29, 2014 · The Residual Sum of Squares (RSS) is the sum of the squared residuals. 以下三个概念等价 (我无话可说)：. RSS: Residual Sum of Squares. SSR: Sum of Squared Residuals. SSE: Sum of Squared Errors. R S S = ∑ i = 1 m e i 2 = ∑ i = 1 m ( y i − f ^ ( x i)) 2. WebIf you think about it, that's the reason why the R-square is commonly interpreted as the proportion of variability in Y that can be explained using X, because it divides the explained sum of squares over the total sum of squares, where the ESS is the total sum of squares minus the residual sum of squares (TSS - RSS).
