| 摘 要： | 对多级评分的测验题型,给出了其Bayes模型,把先验分布从无信息先验推广到了更一般的Dirichlet先验分布情形,求出了参数的Bayes估计,指出了其意义,并在不同样本条件下给出了先验分布超参数的估计.

| Abstract: | This paper deals with the Bayesian Model of multi-grade scored items. The prior distribution is generalized from non-information to what is more generally known as Dirichlet. The Bayesian estimates are provided with their significance. The estimates of super-parameters of prior distribution are also given under different sample conditions. |
