ABC with composite score functions

My friends Erlis Ruli, Nicola Sartori and Laura Ventura from Università degli Studi de Padova have just arXived a new paper entitled Approximate Bayesian Computation with composite score functions. While the paper provides a survey of composite likelihood methods, the core idea of the paper is to use the score function (of the composite likelihood) […]

Lindley’s paradox(es) and scores

“In the asymptotic limit, the Bayesian cannot justify the strictly positive probability of H0 as an approximation to testing the hypothesis that the parameter value is close to θ0 — which is the hypothesis of real scientific interest” While revising my Jeffreys-Lindley’s paradox paper for Philosophy of Science, it was suggested (to me) that I […]

Core [still] minus one…

Another full day spent working with Jean-Michel Marin on the new edition of Bayesian Core (soon to be Bayesian Essentials with R!) and the remaining hierarchical Bayes chapter… I have reread and completed the regression and GLM chapters, sent to very friendly colleagues for a last round of comments. Now, I am essentially idle, waiting […]

Core minus one!

Jean-Michel Marin visited me in Paris last week and, besides taking part in Pierre’s PhD defence, we made enough progress to close two more chapters of the new edition of Bayesian Core (soon to be Bayesian Essentials with R!) This follows the good work session we had in Carnon where we also completed two chapters […]

Carnon [and Core, end]

Yet another full day working on Bayesian Core with Jean-Michel in Carnon… This morning, I ran along the canal for about an hour and at last saw some pink flamingos close enough to take pictures (if only to convince my daughter that there were flamingos in the area!). Then I worked full-time on the spatial […]
