In statistics, the generalized Pareto distribution (GPD) is a family of continuous probability distributions. It is often used to model the tails of another distribution.

The Generalized Pareto distribution (GP) was developed as a distribution that can model tails of a wide variety of distributions, based on theoretical arguments. One approach to distribution fitting that involves the GP is to use a non-parametric fit (the empirical cumulative distribution function, for example) in regions where there are many observations, and to fit the GP to the tail(s) of

The Generalized Pareto distribution was satisfactorily fitted in all months and can be used to provide maximum rainfall extreme levels. No positive trend and temporal dependence of monthly maximum rainfall was found. The rainfall estimates from January to December were calculated for the return periods of 2, 5, 10, 30, 50 and 100 years.

Generalized Pareto distribution is similar to these topics: Skewed generalized t distribution, Davis distribution, Gamma distribution and more.

The distributions are conveniently nested within a single four parameter distribution, the generalized beta of the second type. This relationship facilitates analysis and comparisons. Pareto Distributions. Bartonsville: International Cooperative

The generalized Pareto distribution allows a continuous range of possible shapes that includes both the exponential and Pareto distributions as special cases. You can use either of those distributions to model a particular dataset of exceedances.

(1997) and in Wikipedia; see also Kleiber and Kotz (2003, section 3.12). One may most likely compute quantities for the latter using functions for the Pareto distribution with the appropriate change of parametrization.
