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…

A Poisson Mixed Model with Nonnormal Random Effect Distribution
Lizandra C. Fabio, Gilberto A. Paula, Mario de Castro
We propose in this paper a random intercept Poisson model in which the random effect distribution is assumed to follow a generalized log-gamma (GLG) distribution. We derive the fir…
