Dunsona,2 aDepartment of Statistical Science, Box 90251, Duke University, Durham, NC, 27708, USA Abstract We focus on Bayesian variable selection in regression models. One challenge is to search the Bayesian variable selection which include SSVS as a special case.

Given a training set the goal of variable selection is to detect which variables are important for prediction. The key assumption is that the best possible prediction 

These Bayesian methods have been successfully applied to model selection for supersaturated designs (Beattie et al.

Navas and C. Ordonez and V. Baladandayuthapani}, journal={2010 IEEE International Conference on Data Mining}, year={2010 The selection of variables in regression problems has occupied the minds of many statisticians. Several Bayesian variable selection methods have been developed, and we concentrate on the following methods: Kuo & Mallick, Gibbs Variable Selection (GVS), Stochastic Search Variable Selection (SSVS), adaptive shrinkage with Jeffreys' prior or a Laplacian prior, and reversible jump MCMC. We review The SSVSforPsych project, led by Dr. Bainter, is focused on developing Stochastic Search Variable Selection (SSVS) for identifying important predictors in psychological data and is funded by a Provost Research Award. variables selection in multiclass logistic regression. 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.
