Roberts, James S.; Donoghue, John R.; Laughlin, James E.
Applied Psychological Measurement, v26 n2 p192-207 Jun 2002
Investigated the data demands associated with the marginal maximum likelihood (MML) expected a posterior (EAP) methodology and the precision of the resulting parameter estimates when data fit the underlying model through simulation. Also studied the extent to which a misspecified prior distribution would affect the item and person parameter estimates derived from the MML/EAP technique. Discusses the accurate results resulting from the MML/EAP method. (SLD)
