Adjusting exchangeable beliefs
可交换信念的调整
We consider geometrically the practical, theoretical and computational treatment of second-order exchangeability within Bayes linear analysis. We establish Bayes linear sufficiency for sample means through the representation theorem for second-order exchangeable beliefs. Interrelationships between collections of Bayes linear belief adjustments are analysed through the resolution transforms induced by a second-order exchangeable sample. It is shown that the resolution…
