Two discussions of the paper "Bayesian measures of model complexity and fit" by D. Spiegelhalter et al., Read before The Royal Statistical Society at a meeting organized by the Research Section on Wednesday, March 13th, 2002

It provides insights for statisticians and researchers in Bayesian modeling, but is incremental as it discusses prior work.

This paper presents discussions on Bayesian measures of model complexity and fit, addressing the problem of evaluating and comparing statistical models, with results including critiques and extensions of existing methods.
