"the mean absolute error is similar to variance"?[edit]
Mean absolute error has the same units as the quantity being measured, so it's more like standard deviation than variance, isn't it? Parksy 18:38, 5 April 2007 (UTC)
- I think the same way. I hope someone can talk about it a little bit more. Jackzhp 11:53, 30 May 2007 (UTC)
MAE is homogeneous to the standard deviation (same unit if you wish). However, the behavior of the two indicators is somewhat different.--Joannes Vermorel (talk) 08:35, 8 May 2012 (UTC)
same as mean unsigned error?[edit]
Is the mean absolute error sometimes called mean unsigned error (MUE)? Or is there a difference? — Preceding unsigned comment added by 178.198.95.238 (talk) 10:42, 14 July 2013 (UTC)
Optimality property[edit]
We don't seem to define m before the sentence: "Provided that the probability distribution of X is such that the above expectation exists, then m is a median of X if and only if m is a minimizer"? Or maybe I'm missing something. Is m the MAE? Lionfish0 (talk) 07:53, 30 September 2022 (UTC)
