Not many this week, but there’s a great read.

A Flexible Method of Estimating Luminosity Functions [my subjective comment is added at the bottom] - [stat.ME:0805.3220] Bayarri, Berger, Datta
Objective Bayes testing of Poisson versus inflated Poisson models (will it be of use when one is dealing with many zero background counts, underpopulated above zero background counts, and underpopulated source counts?)
[Comment] You must read it. It can serve as a very good Bayesian tutorial for astronomers. I think there’s a typo, nothing major, plus/minus sign in the likelihood, though. Tom Loredo kindly has informed through his extensive slog comments about Schechter function and this paper made me appreciate the gamma distribution more. Schechter function and the gamma density function share the same equation although the objective of their use does not have much to be shared (Forgive my Bayesian ignorance in the extensive usage of gamma distribution except the fact it’s a conjugate of Poisson or exponential distribution).
FYI, there was another recent arxiv paper on zero-inflation [stat.ME:0805.2258] by Bhattacharya, Clarke, & Datta
A Bayesian test for excess zeros in a zero-inflated power series distribution
