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…
A Bimodal Weibull Distribution: Properties and Inference
Roberto Vila, Mehmet Niyazi Çankaya
Modeling is a challenging topic and using parametric models is an important stage to reach flexible function for modeling. Weibull distribution has two parameters which are shape $…
Sharp Phase Transition for the Random-Cluster Model with Summable External Magnetic Field
Roberto Vila
In this paper, we prove sharpness of the phase transition for the random-cluster model in summable positive external fields, with cluster weight q=2,3,..., on the hypercubic lattic…
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…
