For the multiple regression model with error vector following elliptically contoured distribution we propose Bayesian shrinkage estimators under balanced loss function. Comparing a set of competing estimators for the regression vector, it is shown that the shrinkage factor of the Stein estimator is robust with respect to the regression parameters and unknown density generator of elliptical models. The dominance relation of the estimators is also provided.
