Skewed Laplace distributions I: the origins and inter-relation.

Author

Summary, in English

There are numerous asymmetric extensions of the classical Laplace distribution scattered in the literature. In this survey we discuss their origins and inter-relations. In particular, we point out which types of skew Laplace distributions are essentially the same, described in different, albeit equivalent, parametrizations. In a companion paper cite{KP06} we review the properties of classical and geometric infinite divisibility as well as self-decomposability, which are crucial in extending univariate Laplace models to stochastic processes.
