A wide class of prior distributions for the Poisson‐gamma hierarchical model is proposed. Prior distributions in this class carry vague information in the sense that their tails exhibit slow decay. Conditions for the propriety of the resulting posterior density are determined, as well as for the existence of posterior moments of the Poisson rate of either an observed or an unobserved unit.

Poisson-gamma层次模型的一类平坦先验分布

提出了Poisson-gamma层次模型的一大类先验分布。此类中的先验分布在其尾巴显示缓慢衰减的意义上带有模糊的信息。确定产生的后验密度是否适当的条件,以及确定观察到的单元或未观察到的单元的泊松速率的后矩的条件。
