Small-sample corrections for score tests in Birnbaum-Saunders regressions
Artur J. Lemonte, Silvia L. P. Ferrari
In this paper we deal with the issue of performing accurate small-sample inference in the Birnbaum-Saunders regression model, which can be useful for modeling lifetime or reliabili…
Influence diagnostics in Birnbaum-Saunders nonlinear regression models
Artur J. Lemonte
We consider the issue of assessing influence of observations in the class of Birnbaum-Saunders nonlinear regression models, which is useful in lifetime data analysis. Our results g…
Improved maximum likelihood estimators in a heteroskedastic errors-in-variables model
Alexandre G. Patriota, Artur J. Lemonte, Heleno Bolfarine
This paper develops a bias correction scheme for a multivariate heteroskedastic errors-in-variables model. The applicability of this model is justified in areas such as astrophysic…
Bias correction in a multivariate normal regression model with general parameterization
Alexandre G. Patriota, Artur J. Lemonte
This paper develops a bias correction scheme for a multivariate normal model under a general parameterization. In the model, the mean vector and the covariance matrix share the sam…
Birnbaum-Saunders nonlinear regression models
Artur J. Lemonte, Gauss M. Cordeiro
We introduce, for the first time, a new class of Birnbaum-Saunders nonlinear regression models potentially useful in lifetime data analysis. The class generalizes the regression mo…
