Moment-type estimators for a weighted exponential family
Roberto Vila, Helton Saulo
In this paper, we propose and study closed-form moment type estimators for a weighted exponential family. We also develop a bias-reduced version of these proposed closed-form estim…
Family of multivariate extended skew-elliptical distributions: Statistical properties, inference and application
Roberto Vila, Helton Saulo, Leonardo Santos +2
In this paper we propose a family of multivariate asymmetric distributions over an arbitrary subset of set of real numbers which is defined in terms of the well-known elliptically…
A new unit-bimodal distribution based on correlated Birnbaum-Saunders random variables
Roberto Vila, Helton Saulo, Felipe Quintino +1
In this paper, we propose a new distribution over the unit interval which can be characterized as a ratio of the type where and are two correlated Birnbaum-Saun…
Novel closed-form point estimators for a weighted exponential family derived from likelihood equations
Roberto Vila, Eduardo Nakano, Helton Saulo
In this paper, we propose and investigate closed-form point estimators for a weighted exponential family. We also develop a bias-reduced version of these proposed closed-form estim…
Closed-form estimators for an exponential family derived from likelihood equations
Roberto Vila, Eduardo Nakano, Helton Saulo
In this paper, we derive closed-form estimators for the parameters of some probability distributions belonging to the exponential family. A bootstrap bias-reduced version of these…
