基于改进蜂群算法的项目反应理论混合模型参数估计
Modified ABC Based Parameter Estimation of the Mixture IRT Model
摘要
Abstract
A mixture IRT model was proposed which is composed of the testlet response model and the partial credit model for representing the subject and object tests.Meanwhile a modified artificial bee colony algorithm was proposed to estimate the parameters in the mixture model.The comparative experiment results based on the simulate data show that the novel method in this work is feasible and effective.关键词
