Properties of Ability Estimation Methods and Computerized Adaptive Testing.

Wang, Tianyou; Vispoel, Walter P.

Journal of Educational Measurement, v35 n2 p109-35 Sum 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)
