A four parameter generalization of the Weibull distribution capable of modeling a bathtub-
shaped hazard rate function is defined and studied. The beauty and importance of this …

The present article represents a survey on Poisson generated family of distributions. Based
on this family of distribution, several transformations and distributions have been proposed …

In this paper we proposed a new two-parameters lifetime distribution with increasing failure
rate. The new distribution arises on a latent complementary risk problem base. The …

We introduce and study the so-called Kumaraswamy generalized gamma distribution that is
capable of modeling bathtub-shaped hazard rate functions. The beauty and importance of …

For the first time, a five-parameter distribution, called the Kumaraswamy Burr XII (KwBXII)
distribution, is defined and studied. The new distribution contains as special models some …

The log-logistic distribution is widely used in survival analysis when the failure rate function
presents a unimodal shape. Based on the log-logistic and Kumaraswamy distributions, we …

The author proposes a reduced version, with three parameters, of the new modified Weibull
(NMW) distribution in order to avoid some estimation problems. The mathematical properties …

In this paper, we proposed a new two-parameter lifetime distribution with increasing failure
rate, the complementary exponential geometric distribution, which is complementary to the …

We study in detail the so-called beta-modified Weibull distribution, motivated by the wide
use of the Weibull distribution in practice, and also for the fact that the generalization …

We define and study a new generalization of the complementary Weibull geometric
distribution introduced by Tojeiro et al.(J. Stat. Comput. Simul. 84 (2014) 1345–1362). The …
