The goal of this project is to present an extension of the well-known Inverse Gaussian (IG) distribution), which is the distribution of a random variable that can be defined as the time that a Brownian movement takes to reach a certain level by first time. This extension is obtained as the quotient of two independent random variables, one is the IG distribution, and the other is the power…
The purpose of this project is to present a study of inference and Diagnostics analysis in bivariate regression model Birnbaum-Saunders (BS) based on the scale mixture on normal (SMN) distributions.This model represents a robust extension to the context of the bivariate regression model proposed by Rick and Nedelman (1991). This line of study is a supplement to works of Kundu et al. (2010…
The main of this proposal is to present a study of the Birnbaum-Saunders (BS) distribution based on the scale mixture of Normal distribution, where the mixing distribution is the Inverse Gaussina (IG). The resulting distribution is a type of BS distribution, which is an extension of classical BS distribution. Based on this proposal, we reproduce the properties of the classical BS distribu…
The goal of this project is to present a study of estimation and diagnostic analysis for the multivariate log- Birnbaum-Saunders regression models based on {\it scale mixture of skew-normal distributions} (SMSN) (Branco and Dey, 2001): We first will consider a estimation study based on the modified moment method for multivariate Birnbaum-Saunders distributions (based on the symmetric SMS…
We derive here a study of the bivariate Birnbaum-Saunders (BS) by basing it on the bivariate skew-normal (SN) distribution. This resulting bivariate Birnbaum-Saunders distribution is an absolutely continuous distribution whose marginals are a type of generalized univariate Birnbaum-Saunders distributions. We derive its important characteristics and properties. The estimation is based on t…
The main object of this project is to study the Birnbaum-Saunders (BS) distribution based on the scale mixtures of the Skew-Normal distribution. This new family of distributions of lifetimes represents a robust extension of the classical BS distribution that was proposed by Birnbaum-Saunders (1969). Under this perspective, we will study the properties of classic BS (based on norma distri…
