摘要
首先阐述了等级反应模型(Graded Response Model,简称GRM)的原理和算法及其在多级评分中的应用,接着对等级反应模型(GRM)的参数估计进行了一些推导。最后,阐述了等级反应模型项目参数的迭代方法及能力参数的迭代方程,同时对等级反应模型的未来发展作了一些论述。
The article introduces the principle and algorithm of graded response model （ GRM）, as well as its applications in the multiple categories scoring, and then presents some deduction processes of parameter estimation, Item parameter estimation and possible operational iteration equations are suggested. Directions for future research and applications using graded response model are also suggested.
