Multilevel Modeling

Multilevel Modeling is a concise, practical guide to building models for multilevel and longitudinal data.Author Douglas A. Luke begins by providing a rationale for multilevel models; outlines the basic approach to estimating and evaluating a two-level model; discusses the major extensions to mixed-effects models; and provides advice for where to go for instruction in more advanced techniques.Rich with examples, the Second Edition expands coverage of longitudinal methods, diagnostic procedures, models of counts (Poisson), power analysis, cross-classified models, and adds a new section added on presenting modeling results.A website for the book includes the data and the statistical code (both R and Stata) used for all of the presented analyses.
