Bayesian or Non-Bayesian: A Comparison Study of Item Parameter Estimation in the Three-Parameter Logistic Model
Peer reviewed Peer reviewed
Direct linkDirect link
Gao, Furong; Chen, Lisue – Applied Measurement in Education, 2005
Through a large-scale simulation study, this article compares item parameter estimates obtained by the marginal maximum likelihood estimation (MMLE) and marginal Bayes modal estimation (MBME) procedures in the 3-parameter logistic model. The impact of different prior specifications on the MBME estimates is also investigated using carefully…

Computerized Mastery Testing Using Fuzzy Set Decision Theory.
Peer reviewed Peer reviewed
Du, Yi; And Others – Applied Measurement in Education, 1993
A new computerized mastery test is described that builds on the Lewis and Sheehan procedure (sequential testlets) (1990), but uses fuzzy set decision theory to determine stopping rules and the Rasch model to calibrate items and estimate abilities. Differences between fuzzy set and Bayesian methods are illustrated through an example. (SLD)
