About this book
A guide to the questions that change data can actually answer.
Longitudinal research is not simply cross-sectional research repeated over time. It asks whose change matters, how quickly a process unfolds, and which features of a data-generating process can be recovered from a particular design.
This book moves from study design and descriptive foundations to multilevel, structural equation, dynamic, and intensive longitudinal models—always beginning with the substantive question before choosing a method.

Eight parts, one connected argument
The book begins with the logic of repeated measurement, builds the classical and multilevel foundations, then turns to latent-variable, intensive longitudinal, and applied workflows. The full chapter index remains available in the left-hand navigation.
