Advances in Item Analysis

Peer reviewed

Baker, Frank B. – Review of Educational Research, 1977

Recent advances in item analysis have provided greater capabilities for the analysis of tests, but have also significantly increased the gap between the theory and practice of item analysis. This paper traces the lines of development in item analysis under latent trait theory. (MV)

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

Peer reviewed

Harwell, Michael R.; Baker, Frank B. – Applied Psychological Measurement, 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)
