A Comparison of Maximum Likelihood Estimation and Expected A Posteriori Estimation in CAT Using the Partial Credit Model.
Chen, Ssu-Kuang; Hou, Liling; Dodd, Barbara G.
Educational and Psychological Measurement, v58 n4 p569-95 Aug 1998
A simulation study was conducted to investigate the application of expected a posteriori (EAP) trait estimation in computerized adaptive tests (CAT) based on the partial credit model and compare it with maximum likelihood estimation (MLE). Results show the conditions under which EAP and MLE provide relatively accurate estimation in CAT. (SLD)
