I'm not sure why you feel that is the "real" reason. It is a strong one, of course, but the fact that the squared error has a derivative - and a nice and simple

I'm not sure why you feel that is the "real" reason. It is a strong one, of course, but the fact that the squared error has a derivative - and a nice and simple one - is equally strong in my opinion.
- yummyfajitas 11y agoHaving a derivative is computationally nice. But if your error term is not normal, that only means you can easily compute the wrong answer. I.e. its great if you dropped your key under the lamppost, but the existence of the lamppost doesn't make it a good place to search.
