项目反应理论下等值方法——在Samejima模型下,用比准则求解等值系数

The Equating Method Based on Item Response Theory——Using Compare Rule to Gat Equating Parameters in Samejima Model

本文首先介绍了项目反应理论的优势、项目反应模型及一些等值的方法,然后详细用R方法对Samejima等级反应模型进行处理和模拟,以检测其误差及优劣性。

The essay introduces the superiority of item response theory,the models of item response theory and a series of new equating methods.Then, a uniform procedure based on method of R in Samejima Graded Reponsed Model,which improved the computing efficiency and tested the quality of the method is given.
