摘要
在项目反应理论(IRT)框架下,就目前流行的若干能力参数和项目参数的估计方法进行分析比较,阐述了它们各自适用的范围和不足之处,为选用估计方法提供依据.
In this paper, a number of ways to estimate the latent trait and item parameters was introduced and their advantages and disadvantages were analyzed to offer reliance for selecting fitting method based on item response theory.
