A dual class of the multivariate distributions of Marshall-Olkin type is introduced, and their copulas are presented and utilized to derive explicit expressions of the distributional tail dependencies, which describe the amount of dependence in the upperorthant tail or lower-orthant tail of a multivariate distribution and can be used in the study of dependence among extreme values. A sufficient...
