WebJun 4, 2024 · $\begingroup$ @naught Every distribution has tails. The "right tail" is described by the survival function and the "left tail" by the distribution function, both of which always exist.

But each heavy-tailed distribution gives rise to a different distribution on eigenvalues. With apologies to Tolstoy, thin-tailed matrices are all alike; every thick-tailed matrix is thick-tailed in its own way.

This is a consequence of heights having a thin-tailed probability distribution. Thin, medium, and thick tails all behave differently for the attribution problem as we will show below.

WebFat-Tailed versus Thin-Tailed Uncertainty A thin-tailed probability distribution is one for which the upper tail declines to zero expo-nentially or faster. Such a distribution has a moment generating function, and all moments exist. An example of a thin-tailed distribution that I use in this article is the exponential distribution. WebFeb 29, 2016 · The fifth plot shows the contrasting phenomenon where there is more data concentrated in the center of the distribution and less data in the tails. These “thin tails” correspond to the first quantiles occurring at larger than expected values and the last quantiles occurring at less than expected values.
A fat-tailed distribution is a probability distribution that exhibits a large skewness or kurtosis, relative to that of either a normal distribution or an exponential distribution. In common usage, the terms fat-tailed and heavy-tailed are sometimes synonymous; fat-tailed is sometimes also defined as a subset of heavy-tailed. Different research communities favor one or the other largely for historical reasons, and may have differences in the precise definition of either.
The excess kurtosis is defined as kurtosis minus 3. There are 3 distinct regimes as described below. Distributions with zero excess kurtosis are called mesokurtic, or mesokurtotic. The most prominent example of a mesokurtic distribution is the normal distribution family, regardless of the values of its parameters.
