Web$\begingroup$ @usεr11852: yes, your sequence of point forecasts would be useless, and in particular, much worse than a flat forecast $\hat{y}=1$ (which is both the mean and the median, so it's optimal for both MAE and MSE). A density forecast is not just a sequence of point forecasts! It's a complete density prediction for each future time point.So we would … In statistics, mean absolute error (MAE) is a measure of errors between paired observations expressing the same phenomenon.
