- An Introduction to the DA-T Gibbs Sampler for the Two-Parameter Logistic (2PL) Model and Beyond Gunter Maris Timo M. Bechger Psicología The DA-T Gibbs sampler is proposed by Maris and Maris (2002) as aBayesian estimation method for a wide variety of Item Response Theory(IRT) models. The present paper provides an expository account of the DATGibbs sampler for the 2PL model. However, the scope is not limited tothe 2PL model. It is demonstrated how the DA-T Gibbs sampler for the 2PLmay be used to build, quite easily, Gibbs samplers for other IRT models.Furthermore, the paper contains a novel, intuitive derivation of the Gibbssampler and could be read for a graduate course on sampling. 2005 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16926208 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.2 Vol.26
