We propose two generalizations of the three-parameters Zenga distribution obtaining two families of distributions with four and five parameters. The generalizations are done starting from two different generalized beta functions and using them as mixing distributions in place of the classical beta. We compare the flexibility of the resulting models with that of the Zenga distribution observing some improvements.

Abstract
We propose two generalizations of the three-parameters Zenga distribution obtaining two families of distributions with four and five parameters. The generalizations are done starting from two different generalized beta functions and using them as mixing distributions in place of the classical beta. We compare the flexibility of the resulting models with that of the Zenga distribution observing some improvements.
