WebNov 12, 2024 · Let us consider the column-vector e with coefficients defined as. e i = x i - y i. for i = 1, ..., n.That is, e is the vector of residuals. Using e, we can say that MSE is equal to 1/n times the squared magnitude of e, or 1/n times the dot product of e by itself:. MSE = (1/n) * e ² = (1/n) * e ∙ e. Alternatively, we can rewrite this MSE equation as follows: WebWhat is Root Mean Square (RMS)?
