Resumo: |
In this dissertation we propose four models to model lifetime data. The fist family of distribution is called Exponentiated Complementary Exponential Geometric distribution (ECEG) and it is obtained by exponentiation of the cumulative distribution of the Complementary Exponential Geometric distribution (CEG) proposed by Louzada et al. (2011) to a new parameter α > 0. The second distribution is used to model lifetime when the population is not homogeneous about the risk of death and it has two subpopulation: one composed by individuals not susceptible by the event and other composed by individuals subjected to the risk. This model, called LECEG, has a long term parameter p related to the proportion of individuals out of risk. The third is the Exponentiated Exponential Geometric (EEG) that uses the same idea of the ECEG, and the fourth is the Exponentiated Complementary Exponential Geometric distribution under N systems (ECEGN) presented in a context of N independent working systems and the fails occurs when some of them fail. |
