重尾分布 Heavy-tailed distribution

(重定向自Heavy tail)

在机率论中,重尾分布英语:Heavy-tailed distribution)是一种机率分布的模型,它的尾部比指数分布还要厚。在许多状况中,通常右边尾部的分布会比较受到重视,但左边尾部比较厚,或是两边尾部都很厚的状况,也会被认为是一种重尾分布。

重尾分布之中,又有两个子类型,分别称为长尾分布(long-tailed distributions)以及次指数分布(subexponential distributions)。

Heavy-tailed distribution 重尾分布

(重定向自Heavy tail)

In probability theory, heavy-tailed distributions are probability distributions whose tails are not exponentially bounded: that is, they have heavier tails than the exponential distribution. In many applications it is the right tail of the distribution that is of interest, but a distribution may have a heavy left tail, or both tails may be heavy.
