Some properties of skew-symmetric distributions

Abstract

The family of skew-symmetric distributions is a wide set of probability density functions obtained by combining in a suitable form a few components which are selectable quite freely provided some simple requirements are satisfied. Intense recent work has produced several results for specific sub-families of this construction, but much less is known in general terms. The present paper explores some questions within this framework, and provides conditions on the above-mentioned components to ensure that the final distribution enjoys specific properties.
