We inhabit a world of both invariant characteristics and continuous change. Modeling and predicting these regularities and changes captivated researchers in recent years and resulted in tremendous advances in the field of measurement. New Methods for the Analysis of Change reveals those new trends and emerging themes.

For example, as little as ten years ago, researchers were using traditional procedures emphasizing interindividual variability that often ignored change which manifests itself in the form of intraindividual variablity. Nearly all the chapters in this volume strongly emphasize intraindividual variablity. In addition, missing data posed a great problem to longitudinal researchers in the past. Now, missing data is recognized as a subdiscipline within statis
