Ordinary least squares (OLS) minimizes the residual sum of squares (RSS) RSS = ∑ i (εi)2 = ε′ε = ∑ i (yi − ˆyi)2. The mean squared deviation (in the version you are using it) equals MSE = RSS n where n is the number of observations. Since n is a constant, minimizing the RSS is equivalent to minimizing the MSE. sonic tails knuckles cream lote peluches

"WebMAE will never be higher than RMSE because of the way they are calculated. They only make sense in comparison to the same measure of error: you can compare RMSE for Method 1 to RMSE for Method 2, or MAE for Method 1 to MAE for Method 2, but you can’t say MAE is better than RMSE for Method 1 because it’s smaller.
