Implementation of Marginal Bayesian Estimation with Four-Parameter Beta Prior Distributions.
Zeng, Lingjia
Applied Psychological Measurement, v21 n2 p143-56 Jun 1997
Proposes a marginal Bayesian estimation procedure to improve item parameter estimates for the three parameter logistic model. Computer simulation suggests that implementing the marginal Bayesian estimation algorithm with four-parameter beta prior distributions and then updating the priors with empirical means of updated intermediate estimates can improve item parameter estimation.
