Posterior contraction rates in Sobolev norms and Bayesian derivative estimation for infinite-dimensional exponential families
Emanuele Dolera, Stefano Favaro, Matteo Giordano
We study posterior contraction in positive-order Sobolev norms and Bayesian derivative estimation for infinite-dimensional exponential families. We embed the natural parameter in a…
The variance of the Pitman--Yor process: a Cifarelli--Regazzini identity and inversion formula
Emanuele Dolera, Stefano Favaro
The celebrated Cifarelli--Regazzini identity for the Dirichlet process and its analytic inversion lie at the foundation of an elegant distributional theory for linear functionals o…
AGILE detection of transient γ-ray emission from the region of the supergiant fast X-ray transient source IGR J17354-3255
Andrea Bulgarelli, Gabriele Panebianco, Vito Sguera +16
Context. On April 14, 2009, the AGILE satellite detected a γ-ray flare from an unknown transient source. Subsequent X-ray follow-up observations with Swift and INTEGRAL identified…
A Central Limit Theorem for the Ewens-Pitman random partition in the large- regime via a martingale approach
Bernard Bercu, Claudia Contardi, Emanuele Dolera +1
The Ewens-Pitman model defines a distribution on random partitions of , with parameters and ; the case reduces to the classical Ewens…
Gaussian credible intervals in Bayesian nonparametric estimation of the unseen
Claudia Contardi, Emanuele Dolera, Stefano Favaro
The unseen-species problem assumes samples from a population of individuals belonging to different species, possibly infinite, and calls for estimating the number $K_{n,m}…
Laws of large numbers and central limit theorem for Ewens-Pitman model
Claudia Contardi, Emanuele Dolera, Stefano Favaro
The Ewens-Pitman model is a distribution for random partitions of the set , with , indexed by parameters and , such that $α=0…
