Two–Parameter Logistic IRT Model with Latent Classes
Internaional Conference on Computer Systems and Technlologies – CompSysTech'2006, Veliko Tarnovo
: In this paper we consider the well known two-parameter logistic model from the Item Response Theory (IRT) and suppose the presence of several latent classes among the test population which classes differ each other in the item parameter structure. We give a computer implementation of this model and also empirically examine the model by means of a software test simulator. Parameters are estimated via the MMLE/EM method.
