WebMar 30, 2024 · Simply taking the mean of the residuals squared (as other answers have suggested) is the equivalent of dividing by n instead of ( n - k - 1 ). I would calculate RMSE by sqrt (sum (res$residuals^2) / res$df). The quantity in the denominator res$df gives you the degrees of freedom, which is the same as ( n - k - 1 ). WebFeb 13, 2024 · Sum of squared residuals (SSR) for model 1 S S R 1 = min (over a, b) ∑ i ϵ i 2 subject to y i = a + b x i + ϵ i b = 0 Sum of squared residuals (SSR) for model 2 S S R 2 = min (over a, b) ∑ i ϵ i 2 subject to y i = a + b x i + ϵ i The additional restriction b = 0 can't make the minimum lower! Hence S S R 1 ≥ S S R 2. factor sheets https://gizardman.com
