Using Parameter Expansion to Improve the Performance of the EM Algorithm for Multidimensional IRT Poate convergence using parameter extended EM (PX-EM), a recent modification of the EM algorithm. The PX-EM modification is simple to implement for the IRT survey model and reduces the number of required iterations by approximately one-half without adding any appreciable computation to each EM-iteration.

This chapter provides a formal description of ERFs and briefly illustrates their application to the Rasch model for binary item responses.

Patricia L. Roberts MD, FACS, FASCRSion techniques is compared to the incomplete design strategy, in the case of item nonresponse. The latter strategy results in slightly better ability estimates, but imputation is almost as good, especially when it is based on IRT models.
