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…
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…
A model for risk assessment of a large earthquake with application to Chilean data
Raúl Fierro, Víctor Leiva
We study the asymptotic distribution for the occurrence time of the next large earthquake, by knowing the last large seismic event occurred a long time ago. We prove that, under re…
