Heavy tail
WebThe wiki page on Heavy-tailed distribution defines "fat tail" as anything which follows a power law at extreme values. They also have a technical definition for "long tail", which doesn't match up to the content of long tail, same with the fat tail. Anecdotally I tend to think of "fat tail" as having to do with the severity of the event; for ... WebUpper Tail (Right Tail) Similarly, the upper tail contains the upper values in a distribution. If you graph any distribution on a Cartesian plane, the highest numbers will always appear on the right, because the highest values on a number line are to the right. So, “upper tail” means the same thing as “right tail”. References. Gonick, L ...
