Workshop -- Hierarchical Linear Models (HLM) Redux


This workshop will provide a series of examples of how multilevel modeling can be applied to a variety of research problems and questions.  An introduction to multilevel modeling will be followed by several demonstrations of the use of multilevel modeling methods to address different research problems.  Many social and natural phenomena have a nested or clustered organization.  Hierarchical Linear Modeling (HLM) provides a method for correctly analyzing such data as well as a means to study relationships that occur across levels. Workshop participants will learn foundational principles and concepts in HLM including model testing, fixed and random effects, parameter reliability, and empirical Bayes estimation.  Participants will see a variety of applications of HLM to research problems including estimation of the intraclass correlation coefficient, separating individual from school effects, the study of development and growth, and the use of HLM for meta-analysis.
