WebJul 1, 2024 · In R syntax we can do this with residuals (lm (weight ~ height)). Separately from the confusion about ANOVA, you make the wrong assumption that RSS ≤ TSS always holds. However, a model can be worse than predicting the overall mean (think about predicting values at random); then the residual sum of squares can be greater than the … The explained sum of squares, defined as the sum of squared deviations of the predicted values from the observed mean of y, is. Using in this, and simplifying to obtain , gives the result that TSS = ESS + RSS if and only if .
