Objective Bayes testing of Poisson versus inflated Poisson models
M. J. Bayarri, James O. Berger, Gauri S. Datta
The Poisson distribution is often used as a standard model for count data. Quite often, however, such data sets are not well fit by a Poisson model because they have more zeros tha…
A Bayesian test for excess zeros in a zero-inflated power series distribution
Archan Bhattacharya, Bertrand S. Clarke, Gauri S. Datta
Power series distributions form a useful subclass of one-parameter discrete exponential families suitable for modeling count data. A zero-inflated power series distribution is a mi…
Nonsubjective priors via predictive relative entropy regret
Trevor J. Sweeting, Gauri S. Datta, Malay Ghosh
We explore the construction of nonsubjective prior distributions in Bayesian statistics via a posterior predictive relative entropy regret criterion. We carry out a minimax analysi…
