Notes on the Parameter estimation of some IRT Models by Means of the EM-Algorithm


Христов, Любомир (2017) Notes on the Parameter estimation of some IRT Models by Means of the EM-Algorithm SMB, 2017


 In this paper we consider an implementation of the EM-algorithm to the parameter estimation of some IRT models. The scheme is described in major important details. We point out an online author’s realization of the above approach for various particular IRT models, including the binary logistic models with one, two and three parameters (1PL, 2PL, 3PL), the nominal response model (NRM), the partial credit model (PCM) and the generalized partial credit model (GPCM).
