Bivariate Simplex Distribution
Emerson Amaral, Lucas S. Vieira, Lizandra C. Fabio +2
This article proposes a bivariate Simplex distribution for modeling continuous outcomes constrained to the interval , which can represent proportions, rates, or indices. We…
A novel multivariate regression model for unbalanced binary data : a strong conjugacy under random effect approach
Lizandra C. Fabio, Vanessa Barros, Cristian Villegas +1
In this paper, we deduce a new multivariate regression model designed to fit correlated binary data. The multivariate distribution is derived from a Bernoulli mixed model with a no…
Diagnostic tools for a multivariate negative binomial model for fitting correlated data with overdispersion
Lizandra Castilho Fabio, Cristian Villegas, Jalmar M. F. Carrasco +1
We focus on the development of diagnostic tools and an R package called MNB for a multivariate negative binomial (MNB) regression model for detecting atypical and influential subje…
Errors-in-variables beta regression models
Jalmar M. F. Carrasco, Silvia L. P. Ferrari, Reinaldo B. Arellano-Valle
Beta regression models provide an adequate approach for modeling continuous outcomes limited to the interval (0,1). This paper deals with an extension of beta regression models tha…
