摘要
本研究运用蒙特卡罗模拟方法。在80种不同的实验条件下产生被试的反应矩阵,再分别用信号检测理论(SDT)和项目反应理论(IRT)中的Rasch模型、三参数逻辑斯谛模型对被试的能力进行估计,其结果表明,用这三种不同方法所得到的能力估计值均与能力的真实值有较高的相关。
Response matrixes of subjects were generated with Monte Ca?lo appr- oach under 80 experimental conditions, and the subjects' abilities were estimated with signal detection theory (SDT), Rasch model and three- parameter Logistic model of item response theory (IRT) respectively. The results showed that there was a high correlation between the true abilities. And those estimated by any of the three methods.
