Bayesian Estimation of Normal Ogive Item Response Curves Using Gibbs Sampling.
Albert, James H.
Journal of Educational Statistics, v17 n3 p251-69 Fall 1992
Estimating item parameters from a two-parameter normal ogive model is considered using Gibbs sampling to simulate draws from the joint posterior distribution of ability and item parameters. The method gives marginal posterior density estimates for any parameter of interest, as illustrated using data from a 33-item mathematics placement examination. (SLD)
