Pickands–Balkema–de Haan theorem (Pickands, 1975; Balkema and de Haan, 1974) states that for a large class of underlying distribution functions , and large , is well approximated by the generalized Pareto distribution (GPD), which motivated Peak Over Threshold (POT) methods to estimate : the GPD plays the key role in POT approach.
The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, [2] is a power-law probability distribution that is used in description of social, quality control, scientific, geophysical, actuarial, and many other types of observable phenomena; the principle originally applied to describing the distribution of wealth in a society, fitting the trend ...
The generalized Pareto distribution has a support which is either bounded below only, or bounded both above and below The metalog distribution , which provides flexibility for unbounded, bounded, and semi-bounded support, is highly shape-flexible, has simple closed forms, and can be fit to data using linear least squares.

The q-exponential is a special case of the generalized Pareto distribution where =, =, = (). The q-exponential is the generalization of the Lomax distribution (Pareto Type II), as it extends this distribution to the cases of finite support.
In statistics, a multivariate Pareto distribution is a multivariate extension of a univariate Pareto distribution. [1] There are several different types of univariate Pareto distributions including Pareto Types I−IV and Feller−Pareto. [2] Multivariate Pareto distributions have been defined for many of these types.

The distributions referred to as "Generalized Pareto" are not always the same. The distribution known in classic extreme vale theory (McNeil et al) as a GPD is referred to elsewhere as the "Extremal Pareto" (Kreps) which is the standard two-parameter Pareto with a redefinition of the shape parameter. Compare that with the Klugman-Panjer-Wilmot GPD.
