A new lifetime model with decreasing failure rate
Wagner Barreto-Souza, Hassan S. Bakouch
In this paper we introduce a new lifetime distribution by compounding exponential and Poisson-Lindley distributions, named exponential Poisson-Lindley distribution. Several propert…
The exp- family of probability distributions
Wagner Barreto-Souza, Alexandre B. Simas
In this paper we introduce a new method to add a parameter to a family of distributions. The additional parameter is completely studied and a full description of its behaviour in t…
Improved estimators for dispersion models with dispersion covariates
Alexandre B. Simas, Andréa V. Rocha, Wagner Barreto-Souza
In this paper we discuss improved estimators for the regression and the dispersion parameters in an extended class of dispersion models (Jørgensen, 1996). This class extends the re…
