PARAMETER ESTIMATION FOR THE TWO-PARAMETER MODEL FROM THE ITEM RESPONSE THEORY


Христов, Любомир (2010) PARAMETER ESTIMATION FOR THE TWO-PARAMETER MODEL FROM THE ITEM RESPONSE THEORY Mayan readings of Union of Scientists in Bulgaria, Veliko Tirnovo 2010


 In this paper we consider the classical 2-PL logistic model from the Item Response Theory and present a parameter estimation technique based on the EM-algorithm. Also we present both a MCMC method based on WinBUGS solutions and straightforward Gibbs sampler solution.
