New Results on an Improved Parallel EM Algorithm for Estimating Generalized Latent Variable Models,l diagnostic model (GDM) is presented. This new development further improves the performance of the parallel-E parallel-M algorithm presented in an earlier report by means of additional computational improvements that produce even larger gains in performance. The additional gain achieved by this sec
