摘要

It is well known that the standard Laplace distribution arises by taking the difference of two independent exponential random variables. In this note, a class of generalized Laplace distributions is introduced by taking the difference of two independent exponentiated exponential variables. The various properties of this class of generalized Laplace distributions, which are presented here, include its stochastic representations and moments.
