insufficient statistics for ABC model choice

October 17, 2014

[Here is a revised version of my comments on the paper by Julien Stoehr, Pierre Pudlo, and Lionel Cucala, now to appear [both paper and comments] in Statistics and Computing special MCMSki 4 issue.] Approximate Bayesian computation techniques are 2000’s successors of MCMC methods as handling new models where MCMC algorithms are at a loss, […]

insufficient statistics for ABC model choice

February 12, 2014

Julien Stoehr, Pierre Pudlo, and Lionel Cucala (I3M, Montpellier) arXived yesterday a paper entitled “Geometric summary statistics for ABC model choice between hidden Gibbs random fields“. Julien had presented this work at the MCMski 4 poster session.  The move to a hidden Markov random field means that our original approach with Aude Grelaud does not […]

ABC and sufficient statistics

July 8, 2011

Chris Barnes, Sarah Filippi, Michael P.H. Stumpf, and Thomas Thorne posted a paper on arXiv on the selection of sufficient statistics towards ABC model choice. This paper, called Considerate Approaches to Achieving Sufficiency for ABC model selection, was presented by Chris Barnes during ABC in London two months ago. (Note that all talks of the meeting […]

Sufficient statistics for ABC

November 20, 2008

The issue of picking quasi-sufficient statistics in ABC algorithms is quite important and Joyce and Marjoram have published (last August, sorry I’m late!) a proposal in Statistical Applications in Genetics and Molecular Biology that is addressing this issue, at least to the extend that the inclusion of a new statistics within the set of summary […]

Bayesian restricted likelihood with insufficient statistic [slides]

February 9, 2022

A great Bayesian Analysis webinar this afternoon with well-balanced presentations by Steve MacEachern and John Lewis, and original discussions by Bertrand Clarke and Fabrizio Rugieri. Which attracted 122 participants. I particularly enjoyed Bertrand’s points that likelihoods were more general than models [made in 6 different wordings!] and that this paper was closer to the M-open […]
