"the mean absolute error is similar to variance"?

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)[reply]

I think the same way. I hope someone can talk about it a little bit more. Jackzhp 11:53, 30 May 2007 (UTC)[reply]

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)[reply]

same as mean unsigned error?

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)[reply]

Optimality property

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)[reply]
