- Exponentiated extended Weibull-power series class of distributions S. Tahmasebi A. A. Jafari Estudios Ambientales EM algorithm Exponentiated family Power series distributions Maximum likelihood e stimation In this paper, we introduce a new class of distributions by co mpounding the exponentiated extended Weibull family and power series family. This distribution contains several li fetime models such as the complementary extended Weibull-p ower series, generalized exponential-power series, generaliz ed linear failure rate-power series, exponentiated Weibul l-power series, generalized modified Weibull-power series, generalized Go mpertz-power series and exponentiated extended Weibull di stribu- tions as special cases. We obtain several properties of this new class of distributions such as Shannon entropy, mean res idual life, hazard rate function, quantiles and moments. The maxi mum likelihood estimation procedure via a EM-algorithm is presented. 2015 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467546186001 en http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.2 Vol.37
