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…

A new mixture-based fixed-effect model for a biometrical case-study related to immunogenecity with highly censored data
Mário F. Desousa, Helton Saulo, Manoel Santos-Neto +1
We propose a new continuous-discrete mixture regression model which is useful for describing highly censored data. We motivate our investigation based on a case-study in biometry r…

On a bivariate Birnbaum-Saunders distribution parameterized by its means: features, reliability analysis and application
Helton Saulo, Jeremias Leão, Roberto Vila +2
Birnbaum-Saunders models have been widely used to model positively skewed data. In this paper, we introduce a bivariate Birnbaum-Saunders distribution which has the means as parame…
