In statistics, the term long-tailed distribution has a narrow technical meaning, and is a subtype of heavy-tailed distribution.[2][3][4] Intuitively, a distribution is (right) long-tailed if, for any fixed amount, when a quantity exceeds a high level, it almost certainly exceeds it by at least that amount: large quantities are probably even larger.[lower-alpha 1] Note that there is no sense of the "long tail" of a distribution, but only the property of a distribution being long-tailed.
