Similarity analysis in Bayesian random partition models
(ELSEVIER, 2011)
This work proposes a method to assess the influence of individual observations in the clustering generated by any process that involves random partitions. We call it Similarity Analysis. It basically consists of decomposing ...
A bayesian analysis for the parameters of the exponential-logarithmic distribution
(2013-07-01)
The exponential-logarithmic is a new lifetime distribution with decreasing failure rate and interesting applications in the biological and engineering sciences. Thus, a Bayesian analysis of the parameters would be desirable. ...

Bayesian density estimation for compositional data using random bernstein polynomials
(2015)
We propose a Bayesian nonparametric procedure or density estimation for data in a d-dimensional simplex. To this aim, we propose a prior distribution on probability measures based on a modified class of multivariate Bernstein ...
Multicollinearity and financial constraint in investment decisions: a bayesian generalized ridge regression
(2011)
This paper addresses the investment decisions considering the presence of financial constraints of 373 large Brazilian firms from 1997 to 2004, using panel data. A Bayesian econometric model was used considering ridge ...
Flexible Univariate Continuous Distributions
(INT SOC BAYESIAN ANALYSIS, 2009)
Based on a constructive representation, which distinguishes between a skewing mechanism P and an underlying symmetric distribution F, we introduce two flexible classes of distributions. They are generated by nonparametric ...
