The distribution due to Okorie et al. (2016) is further extended to a wider family of distribution called the Kumaraswamy Generalized Exponentiated Gumbel type-2 distribution. Twenty two distributions are identified as sub-models of the new distribution. Some of its important statistical properties are explicitly derived and the parameters of the new distribution are estimated through the method of maximum likelihood estimation.


Une distribution de probabilité proposée par Okorie et al. (2016) est étendue à une large famille de function de répartitions dénommée Distribution Généralisée Exponen- tielle Gumbel-Exponentielle de kumaraswamy de Type-2 distribution qui regroupe au moins vingt-deux en tant que sous-modèles. Une série de proptiétés statistiques importantes de cette famile sont étudiées, parmi lesquelles l'estimation de paramètres par la méthode du maximum de vraisemblance.
