Bayesian Procedures for Identifying Aberrant Response-Time Patterns in Adaptive Testing
Peer reviewed Peer reviewed
Direct linkDirect link
van der Linden, Wim J.; Guo, Fanmin – Psychometrika, 2008
In order to identify aberrant response-time patterns on educational and psychological tests, it is important to be able to separate the speed at which the test taker operates from the time the items require. A lognormal model for response times with this feature was used to derive a Bayesian procedure for detecting aberrant response times.…

The Validity of the GMAT for the Prediction of Grades in Doctoral Study in Business and Management: An Empirical Bayes Approach.
Peer reviewed Peer reviewed
Zwick, Rebecca – Journal of Educational Statistics, 1993
A validity study with 5,219 students examined the degree to which Graduate Management Admission Test (GMAT) scores and undergraduate grade point average (GPA) could predict first-year average and final GPA in doctoral programs in business. The usefulness of the predictions derived from the empirical Bayes regression models is discussed. (SLD)
