Peer reviewedMuraki, Eiji; Carlson, James E. – Applied Psychological Measurement, 1995
A full-information item factor analysis model for multidimensional polytomously scored item response data is developed as an extension of previous work by several authors. The model is expressed in factor-analytic and item response theory parameters, and an EM algorithm for estimation of the model parameters is presented. (SLD)
