Asymptotics for posterior hazards
Pierpaolo De Blasi, Giovanni Peccati, Igor Prünster
An important issue in survival analysis is the investigation and the modeling of hazard rates. Within a Bayesian nonparametric framework, a natural and popular approach is to model…
Bayesian nonparametric estimators derived from conditional Gibbs structures
Antonio Lijoi, Igor Prünster, Stephen G. Walker
We consider discrete nonparametric priors which induce Gibbs-type exchangeable random partitions and investigate their posterior behavior in detail. In particular, we deduce condit…
On rates of convergence for posterior distributions in infinite-dimensional models
Stephen G. Walker, Antonio Lijoi, Igor Prünster
This paper introduces a new approach to the study of rates of convergence for posterior distributions. It is a natural extension of a recent approach to the study of Bayesian consi…
Distributions of linear functionals of two parameter Poisson--Dirichlet random measures
Lancelot F. James, Antonio Lijoi, Igor Prünster
The present paper provides exact expressions for the probability distributions of linear functionals of the two-parameter Poisson--Dirichlet process . We o…
Normalized random measures driven by increasing additive processes
Luis E. Nieto-Barajas, Igor Prunster, Stephen G. Walker
This paper introduces and studies a new class of nonparametric prior distributions. Random probability distribution functions are constructed via normalization of random measures d…
