Multilevel Models in Educational and Social Research by Harvey Goldstein
This general methodological discussion presents the essential features of multilevel modelling. The models described solve a number of problems in different fields, including the social and biological sciences, where data have a hierarchical structure. Practical examples are used to illustrate topics such as school effectiveness, progress in reading achievement, child growth, and social attitudes. A basic familiarity with structure and application of linear or multiple regression models is assumed.
