method, called stochastic search variable selection. Some other Bayesian methods related to stochastic search vari-able selection were studied by Chipman (1996), Chipman et al. (1997), and George and McCulloch (1997). These Bayesian methods have been successfully applied to model selection for supersaturated designs (Beattie et al. 2002),

(2008). The basic idea of SSVS is to assign commonly used prior variances to parameters, which should be included in a model, and prior variances close to zero to irrelevant parameters.

There has been recent work in variable selection methods, including LASSO and one-step SCAD techniques (Buu et al., 2011) and a stochastic variable selection strategy (Cantoni and Auda, 2018).

We perform an empirical comparison of stochastic DCA with DCA and standard methods on very large synthetic and real-world datasets, and show that the stochastic DCA is efficient in group variable selection ability and classifica-tion accuracy as well as running time. In this article, we advocate the ensemble approach for variable selection.

3 Variable selection for stochastic blockmodels The description of relations between pairs of blocks provided by stochastic blockmodels requires the use of a rather large number of parameters. This is necessary in order to model each interaction between blocks (Br,Bs), s≥r∈{1,,p}.

Consider this Bayesian linear regression model.

In this article, we advocate the ensemble approach for variable selection. We point out that the stochastic mechanism used to generate the variable-selection ensemble (VSE) must be picked with care. We construct a VSE using a stochastic stepwise algorithm and compare its performance with numerous state-of-the-art algorithms. Supplemental materials for the article are available online.

This example shows how to implement stochastic search variable selection (SSVS), a Bayesian variable selection technique for linear regression models. Introduction. Consider this Bayesian linear regression model.
