“This text has artistically balanced ... advanced multilevel concepts and a depth and breadth of topics in a reader-friendly, accessible fashion. ... [It] is poised to make a great splash in the methodological world. ... I have a copy of every text written by these authors and use them consistently for a number of reasons including clarity in writing, comprehensive coverage, and accuracy. This text ... offers these same characteristics. ... Appropriate for graduate level courses ... as well as individual researchers that use multilevel modeling—regardless of discipline.” - Debbie L. Hahs-Vaughn, University of Central Florida, USA“This book is a natural extension to a well-received and highly successful previous project by the same authors. Using essentially the same strategy and approach, this book extends the coverage to advanced models and thereby moves the field even further along. I highly endorse this product." - George Marcoulides, Quantitative Methodology Series Editor, University of California, Riverside, USA“It fills a significant gap in the literature. ... I would purchase this book and recommend it to colleagues who do multilevel modeling with SPSS ... [and] to students who take my courses and workshops. ...The conceptual material is very clear.” - Jason T. Newsom, Portland State University, USA
