"This is a great introductory text with worked examples to guide students and practitioners through analysis and interpretation of multilevel models. The text strikes an effective balance between technical language and applications to demonstrate important concepts." – Grant B. Morgan, Baylor University, USA
"Heck and Thomas provide an introduction to multilevel modeling that is not just comprehensive but also eminently readable. The new edition gives the reader to tackle some of the more recent sophisticated modeling approaches. It is an excellent choice for an instructor looking for a text that helps students to become facile with modeling choices and approaches." – Laura M. Stapleton, University of Maryland, USA
"Developing a basic modeling strategy that researchers can follow to investigate multilevel data structures can be challenging. The authors skillfully present a must-have reference book to get the job done. The easy-to-follow illustrative examples and the extensive software applications are excellent – a masterpiece!" – George A. Marcoulides, University of California, Santa Barbara, USA
"I used the second edition ... in my courses and the improvements for the third edition would be exactly my suggestions. I was especially pleased with the decision to use Mplus. ...The second edition was easy to read and follow―this was the reason that I assigned the book to the students ... in my graduate SEM course. ... I would use the third edition ... in [the same] course." – G. Leonard Burns, Washington State University, USA
"[This] is the only textbook I know of that presents multilevel regression modeling and structural equation modeling as part of a combined framework. ... The revisions ... prepare readers to understand both procedures and to conduct both types of analyses. ... The changes make the book a better teaching tool. ... It would be an excellent choice for students who take my multilevel regression modeling course ... [and] ... my design of experiments course." – Laura M. O’Dwyer, Boston College, USA
"The proposed changes will certainly make the book a better teaching text. ... The narrative ... provides much needed clarity to a difficult to understand topic. ... I would purchase the book for my personal use and I would (and do) include it on a list of recommended resources on multilevel modelling. ...This book is rather unique in the content it covers and the audience it serves. ... It is meeting a need others are not." – Dick Carpenter, University of Colorado, USA
