In 2007, Judkins, Krenzke, Piesse, Fan, and Haung reported on the performance of a new semi-parametric imputation algorithm designed to impute entire questionnaires with minimal human supervision while preserving important first- and second-order distributional properties. In a 2008 paper, we reported on procedures for post-imputation variance estimation to be used in conjunction with the semi-parametric imputation algorithm. In this paper, we discuss recent enhancements to handle very large longitudinal datasets for the Mental Health Treatment Study.
