An Introduction to the DA-T Gibbs Sampler for the Two-Parameter Logistic (2PL) Model and beyond
Maris, Gunter; Bechger, Timo M.
Psicologica: International Journal of Methodology and Experimental Psychology, v26 n2 p327-352 2005
The DA-T Gibbs sampler is proposed by Maris and Maris (2002) as a Bayesian estimation method for a wide variety of "Item Response Theory (IRT) models". The present paper provides an expository account of the DA-T Gibbs sampler for the 2PL model. However, the scope is not limited to the 2PL model. It is demonstrated how the DA-T Gibbs sampler for the 2PL may be used to build, quite easily, Gibbs samplers for other IRT models. Furthermore, the paper contains a novel, intuitive derivation of the Gibbs sampler and could be read for a graduate course on sampling. (Contains 9 figures and 4 footnotes.)
