On a length-biased Birnbaum-Saunders regression model applied to meteorological data
Kessys L. P. Oliveira, Bruno S. Castro, Helton Saulo +1
The length-biased Birnbaum-Saunders distribution is both useful and practical for environmental sciences. In this paper, we initially derive some new properties for the length-bias…
Log-symmetric quantile regression models
Helton Saulo, Alan Dasilva, Víctor Leiva +1
Regression models based on the log-symmetric family of distributions are particularly useful when the response is strictly positive and asymmetric. In this paper, we propose a clas…
On a family of discrete log-symmetric distributions
Helton Saulo, Roberto Vila, Leonardo Paiva +1
The use of continuous probability distributions has been widespread in problems with purely discrete nature. In general, such distributions are not appropriate in this scenario. In…
A bimodal gamma distribution: Properties, regression model and applications
R. Vila, L. Ferreira, H. Saulo +2
In this paper we propose a bimodal gamma distribution using a quadratic transformation based on the alpha-skew-normal model. We discuss several properties of this distribution such…
