Some properties of the family of Koehler Symanowski distributions

In this paper, a class of multivariate distributions introduced by
Koehler and Symanowski (1995) is discussed with regard to whether
it can be reasonably applied in the framework of graphical
modeling. Therefore, the focus lies on properties like marginal and
conditional independence, marginalization and the flexibility as
far as the modeling of a dependence structure is concerned.
