Insufficient Gibbs sampling [at COMPSTAT 2024]

The COMPSTAT 2024 programme proved somewhat remote from my interests, far from the 1998 version I attended that was buzzing and brimming with MCMC sessions! (Correlatively, apart from the speakers in my own session, I hardly knew anyone there.) I however [missed a Bayesian session as I] attended a session on change-point detection, with a talk by Ziyang Yang (Lancaster University) on an acceleration proposal when the data size is too much, by aggregating similar datapoints, for which I would like to see a theoretical analysis of the impact of this aggregation on the quality (and consistency) of the attached Bayes factor. In my own session, I did not feel overly comfortable with the presentation of a commercial [i.e., for sale] software for pharmacokinetics.
I also enjoyed spending the day in Gießen, from running to the top of nearby Burg Glieberg at sunrise to swimming outdoor in the local 50m Freibad.
