Estimation of Item Response Models Using the EM Algorithm for Finite Mixtures [electronic resource] / David J. Woodruff and Bradley A. Hanson.

This paper presents a detailed description of maximum parameter estimation for item response models using the general EM algorithm. In this paper the models are specified using a univariate discrete latent ability variable. When the latent ability variable is discrete the distribution of the observe...
