Doubly Non-Central Generalized Beta Distributions
Authors: , ,
Abstract: The doubly non-central generalized beta type 1 and type 2 distributions have been derived by using two
independent non-central gamma variables with different scale parameters. These distributions generalize several
well known central and non-central beta distributions. The doubly non-central generalized beta densities are much
more flexible than many exiting beta models and can assume a large variety of shapes. Several properties of these
distributions have been studied.
