%description
Create densities, probabilities, random numbers, quantiles, and maximum
likelihood estimation for several distributions, mainly the symmetric and
asymmetric power exponential (AEP), a.k.a. the Subbottin family of
distributions, also known as the generalized error distribution.
Estimation is made using the design of Bottazzi (2004)
<https://ideas.repec.org/p/ssa/lemwps/2004-14.html>, where the likelihood
is maximized by several optimization procedures using the 'GNU Scientific
Library (GSL)', translated to 'C++' code, which makes it both fast and
accurate. The package also provides methods for the gamma, Laplace, and
Asymmetric Laplace distributions.
