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…
On the Ultrametricity Property in Random Field Ising Models
Jamer Roldan, Roberto Vila
In this paper we show that the ultrametricity property remains valid in random field Ising models with independent disorder whenever the field strength is a small perturbation.
