Downloadable (with restrictions)! In this paper, we propose a novel Max-Relevance and Min-Common-Redundancy criterion for variable selection in linear models. Considering that the ensemble approach for variable selection has been proven to be quite effective in linear regression models, we construct a variable selection ensemble (VSE) by combining the presented stochastic correlation


Stochastic search variable selection (SSVS) identifies promising subsets of multiple regression covariates via Gibbs sampling (George and McCulloch 1993). Here’s a short SSVS demo with JAGS and R. Assume we have a multiple regression problem: We suspect only a subset of the elements of $\boldsymbol{\beta}$ are non-zero, i.e.

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), The stochastic search variable selection procedure is a Gibbs sampling scheme where each iteration samples from the conditional distributions [ flj°;Y;¾ ], [ °jfl;Y;¾ ], and [ ¾jY;fl;° ].
