Main Texts

·       Goldstein (1995).  Multilevel Statistical  Models.

·       Hox (1995). Applied Multilevel Analysis.

 

Note: Both texts present a mix of conceptual and quite technical material, all backed by excellent examples.  Concentrate on the concepts and examples, but be sure that you understand the connections between these and the formal models.  Unless you are a Biostatistics graduate student, skip the technical derivations.
