Abstract
This chapter presents the gamma generalized family of distributions proposed by Zofragos and Balakrishnan (2009). Several mathematical properties are provided such as representations for gamma-G density and cumulative functions, some generalized moments, quantile and generating functions and entropies. A bivariate generalization is presented. An application is performed in order to illustrate empirically the usefulness of this family.
Keywords: Gamma-G Model; GGum; GLL; GLN; GN; GW; Mean deviation; Moment; Order statistic.
