| 摘 要： | 项目反应理论（IRT）框架下的等值,目前比较流行的有Stocking-Lord方法和Haebara方法,即使对于相同的项目参数和能力参数,这两种等值方法计算出的等值系数也是不相同的.受Pearson卡方检验的启发,文中导出一种新的求取等值系数方法,即：加权等值方法（Weighted criterion,Wcrit）,它实际上是Haebara准则的加权式.Monte-Carlo模拟结果表明：Stocking-Lord方法和Haebara方法的表现各有千秋,而通常情况下,加权等值方法比Haebara方法表现更优.

| Abstract: | There are some popular equating criteria based on item response theory,such as Stocking-Lord method,Haebara method.The equating coefficients,derived from the different equating method,are not the same even for the same raw data.In this paper,a new method,named Weighted-Haebara method,is proposed in the light of Pearson's Chi-Square Test Statistic.Monte Carlo study shows that Stocking-Lord method and Haebara method.are comparable;usually,the behavior of Weighted-Haebara method is better than that of Haebara method. |
