In this paper, we propose several Bayesian model selection procedures, based on the spike and slab priors, to select significant variables while accounting for some restrictions on them. We concentrate on the following methods: Kuo & Mallick, Stochastic Search Variable Selection(SSVS), Ishwaran & Rao (NMIG). Bayesian computation is straightforward via simple Gibbs sampling algorithm. The methods are illustrated using simulated data and an application to the Blood lead levels data. Results indicate that the proposed approaches perform very well in various situations.
