Parameter Estimation of MIRT Models for Dichotomous Data
-
摘要: 利用DSY算法开发了多维二级评分模型的参数估计程序 ,推广了该类评分模型的参数估计方法 ,比较了MCMC和DSY算法 ,说明了DSY算法能有效估计该类型评分模型的参数 ,提出了一些有待研究的问题 .Abstract: In a study reported in the present paper ,a procedure for estimating the parameters of MIRT models for dichotomous data is developed with the DSY algorithm ,the parameter estimation methods of MIRT models for dichotomous data are generalized ,and the MCMC and the DSY algorithms are com-pared .The results show that the DSY algorithm can effectively estimate parameters of the MIRT models for dichotomous data .Finally ,a few problems to be further studied are outlined .
