Comparing Four Different Statistical Packages for Hierarchical Linear Regression: GENMOD, HLM, ML2, and VARCL
In this report we give an overview of some of the available statistical theory and software for analyzing hierarchically nested data. We evaluate these programs, and we propose a technique that can analyze data of several different domains and is more general than the existing programs.
