Bayesian methods - either based on Bayes Factors or BIC - are now widely used for model selection. One property that might reasonably be demanded of any model
selection method is that if a modelM1 is...

Implementing Bayesian variable selection for linear Gaussian regression models for analysing
high dimensional data sets is of current interest in many fields. In order to make such analysis operation...

In this article I develop a simple and eective device for ascertaining the quality
of the modeling choices and detecting lack-of-fit. I specify an articial autoregres-
