The Weibull-Geometric distribution
Wagner Barreto-Souza, Alice Lemos de Morais, Gauss M. Cordeiro
In this paper we introduce, for the first time, the Weibull-Geometric distribution which generalizes the exponential-geometric distribution proposed by Adamidis and Loukas (1998).…
A Generalization of the Exponential-Poisson Distribution
Wagner Barreto-Souza, Francisco Cribari-Neto
The two-parameter distribution known as exponential-Poisson (EP) distribution, which has decreasing failure rate, was introduced by Kus (2007). In this paper we generalize the EP d…
The Beta Generalized Exponential Distribution
Wagner Barreto-Souza, Alessandro H. S. Santos, Gauss M. Cordeiro
We introduce the beta generalized exponential distribution that includes the beta exponential and generalized exponential distributions as special cases. We provide a comprehensive…
Improved estimators for a general class of beta regression models
Alexandre B. Simas, Wagner Barreto-Souza, Andréa V. Rocha
In this paper we consider an extension of the beta regression model proposed by Ferrari and Cribari-Neto (2004). We extend their model in two different ways, first, we let the regr…
Some results for beta Fréchet distribution
Wagner Barreto-Souza, Gauss M. Cordeiro, Alexandre B. Simas
Nadarajah and Gupta (2004) introduced the beta Fréchet (BF) distribution, which is a generalization of the exponentiated Fréchet (EF) and Fréchet distributions, and obtained the pr…
