摘要
WinGen是一种基于Windows系统下的项目参数、被试以及作答数据的模拟软件,该软件不仅支持众多的单维项目反应模型,也支持多维项目反应模型。研究通过使用WinGen实现被试、项目和作答的蒙特卡罗模拟,并用Bilog对作答数据进行了参数估计,最后通过计算参数估计的各个评价指标,结果表明使用WinGen模拟的数据质量优良,与模型的拟合性较好,可以满足广大测量研究者在不同条件下数据的模拟,研究者可以在模拟数据的基础进行进一步的分析和研究。
WinGen is a Windows -based system which can simulate item parameters, examinees anu response data, and WinGen supports a large number of unidimensional item response models, and also supports multidimensional item response models. Using WinGen to simulate examinees, items and re- sponse by means of Monte Carlo method, and using Bilog to estimate the parameters, calculates several typical criteria to evaluate the data. Results show that the data simulated by WinGen has good quality, and the model fit better, can satisfy the need of researchers under different conditions of data model- ing, researchers can simulate data for further analysis and research.
