Peer reviewedVispoel, Walter P.; Rocklin, Thomas R.; Wang, Tianyou; Bleiler, Timothy – Journal of Educational Measurement, 1999
Investigated the effectiveness of H. Wainer's (1993) strategy for obtaining positively biased ability estimates when examinees can review and change answers on computerized adaptive tests. Results, based on simulation and testing data from 87 college students, show that the Wainer strategy sometimes yields inflated ability estimates and sometimes…

Peer reviewedWang, Tianyou; Vispoel, Walter P. – Journal of Educational Measurement, 1998
Used simulations of computerized adaptive tests to evaluate results yielded by four commonly used ability estimation methods: maximum likelihood estimation (MLE) and three Bayesian approaches. Results show clear distinctions between MLE and Bayesian methods. (SLD)
