从估计试题参数的贝叶斯观点出发，研究了一组二元反应的试题反应曲线。对于具有正态分布能力的双参数Logistic模型，利用受限的双变量贝塔先验来说明EM算法的后验模型的计算。通过一次数学考试的数据说明了这一过程。
Item response curves for a set of binary responses are studied from a Bayesian viewpoint of estimating the item parameters. For the two-parameter logistic model with normally distributed ability, restricted bivariate beta priors are used to illustrate the computation of the posterior mode via the EM algorithm. The procedure is illustrated by data from a mathematics test.
