Modeling double bounded data based on correlated gamma random variables
Roberto Vila, Felipe Quintino, Marcelo Bourguignon
Many types of bounded data defined on the unit interval arise naturally as ratios of the form . In the existing literature, the main statistical models proposed for this…
On the distribution of a random variable involved in an independent ratio
Roberto Vila, Narayanaswamy Balakrishnan, Marcelo Bourguignon
In this paper, using inverse integral transforms, we derive the exact distribution of the random variable that is involved in the ratio where an…
Parametric quantile regression for income data
Helton Saulo, Roberto Vila, Giovanna V. Borges +1
Univariate normal regression models are statistical tools widely applied in many areas of economics. Nevertheless, income data have asymmetric behavior and are best modeled by non-…
The shared weighted Lindley frailty model for cluster failure time data
Diego I. Gallardo, Marcelo Bourguignon
The primary goal of this paper is to introduce a novel frailty model based on the weighted Lindley (WL) distribution for modeling clustered survival data. We study the statistical…
On Some Properties of the Beta Inverse Rayleigh Distribution
J. Leão, H. Saulo, M. Bourguignon +3
We study with some details a lifetime model of the class of beta generalized models, called the beta inverse Rayleigh distribution, which is a special case of the Beta Fréchet dist…
A parametric quantile beta regression for modeling case fatality rates of COVID-19
Marcelo Bourguignon, Diego I. Gallardo, Helton Saulo
Motivated by the case fatality rate (CFR) of COVID-19, in this paper, we develop a fully parametric quantile regression model based on the generalized three-parameter beta (GB3) di…
