Canonical correlations for dependent gamma processes
Dario Spanò, Antonio Lijoi
The present paper provides a characterisation of exchangeable pairs of random measures whose identical margins are fixed to coincide with the distri…
Conditional formulae for Gibbs-type exchangeable random partitions
Stefano Favaro, Antonio Lijoi, Igor Prünster
Gibbs-type random probability measures and the exchangeable random partitions they induce represent an important framework both from a theoretical and applied point of view. In the…
Limiting behavior of the search cost distribution for the move-to-front rule in the stable case
Fabrizio Leisen, Antonio Lijoi, Christian Paroissin
Move-to-front rule is a heuristic updating a list of n items according to requests. Items are required with unknown probabilities (or popularities). The induced Markov chain is kno…
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…
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…
Means of a Dirichlet process and multiple hypergeometric functions
Antonio Lijoi, Eugenio Regazzini
The Lauricella theory of multiple hypergeometric functions is used to shed some light on certain distributional properties of the mean of a Dirichlet process. This approach leads t…
