Whereas for point 1, the error is positive and of almost the same magnitude. For point 2 it is 0. Adding all of these up would lead to a total error of 0! But the error is certainly much more than that.

This is typically done by setting the intercept, but you can force the regression line through any point.
WebAug 10, 2024 · What is a good MSE value? The closer your MSE value is to 0, the more accurate your model is. However, there is no 'good' value for MSE. It is an absolute value which is unique to each dataset and can only be used to say whether the model has become more or less accurate than a previous run. WebJun 1, 2024 · So if a model gives you a MAE of say 0.55 and another model gives you a MAE of say 0.78, their NMAE values would be flipped as -0.55 and -0.78 and by following the convention of higher the better, we pick the former model which results has a higher NMAE of -0.55. You can make a similar argument for MSE.
