Overview

The thrust of this research is to improve understanding of estimation of realized random effects. Such estimates are used for domain means, subject effects, and cluster effects. Understanding and estimating these effects is important in analysis of cluster randomized trials. This research is pursued by using superpopulation sampling prediction theory based on a superpopulation generated from a random permutation probabilities.
