讲座摘要：
In this talk, we will present an objective Bayesian analysis for the Student-t linear regression model with unknown degrees of freedom. The reference priors under all the possible group orderings for the parameters in the model are derived. The posterior propriety under each reference prior is validated by considering a larger class of priors. Simulation studies are carried out to investigate the frequentist properties of Bayesian estimators based on the reference priors. Finally, the Bayesian approach is applied to a real data set. This is a joint work with Prof. Dongchu Sun and Dr. Lei He.
