Fundamentals of Hierarchical Linear and Multilevel Modeling
www.sagepub.comLinear mixed models for multilevel analysis address hierarchical data, such as when employee data are at level 1, agency data are at level 2, and department data are at level 3. Hierarchical data usually call for LMM implementation. While most multilevel modeling is univariate (one dependent variable), multivariate multilevel
