"This book is well written in an accessible style, and it will clearly appeal to researchers with a social and psychological interest."—The Statistician"Investigators conducting longitudinal research should find this book useful."—Journal of Mathematical Psychology"...I consider this book to be an extremely useful resource providing a great deal of depth in the topics of multilevel and longitudinal modeling. Because many of the topics included in this book are cutting-edge methodological advances, the book will be most appreciated by researchers who already have a good grasp of multilevel and longitudinal approaches. For this group of individuals, the book will be a very valuable resource.—Organizational Research Methods
