The Use of Prior Distributions in Marginalized Bayesian Item Parameter Estimation: A Didactic.

Harwell, Michael R.; Baker, Frank B.

Applied Psychological Measurement, v15 n4 p375-89 Dec 1991

Previous work on the mathematical and implementation details of the marginalized maximum likelihood estimation procedure is extended to encompass the marginalized Bayesian procedure for estimating item parameters of R. J. Mislevy (1986) and to communicate this procedure to users of the BILOG computer program. (SLD)
