Contact Us 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 ).
