Group-Based Modeling of Development

Daniel S. Nagin

ISBN 9780674016866

Publication date: 04/25/2005

This book provides a systematic exposition of a group-based statistical method for analyzing longitudinal data in the social and behavioral sciences and in medicine. The methods can be applied to a wide range of data, such as that describing the progression of delinquency and criminality over the life course, changes in income over time, the course of a disease or physiological condition, or the evolution of the socioeconomic status of communities. Using real-world research data from longitudinal studies, the book explains and applies this method for identifying distinctive time-based progressions called developmental trajectories. Rather than assuming the existence of developmental trajectories of a specific form before statistical data analysis begins, the method allows the trajectories to emerge from the data itself. Thus, in an analysis of data on Montreal school children, it teases apart four distinct trajectories of physical aggression over the ages 6 to 15, examines predictors of these trajectories, and identifies events that may alter the trajectories.

Aimed at consumers of statistical methodology, including social scientists, criminologists, psychologists, and medical researchers, the book presents the statistical theory underlying the method with a mixture of intuition and technical development.

Praise

  • Nagin's book provides a thorough and accessible treatment of the statistical method for analyzing longitudinal data to which he has contributed so much in the last decade. The hallmark of this method is its identification of a set of distinct trajectories of change over time in order to capture a sample's diversity in patterns of development. Nagin and his colleagues have applied, refined, and extended this approach over the past decade and this book is the culmination that brings it all together.
