Book Description

The analysis of intra-individual variation (IAV) concerns time series analysis applied to human processes such as psychological, psycho-physiological, and disease processes. There are many features unique to this methodology and a need for a book giving an overview of the methods, with examples and software. This book fills that gap, covering all the key topics, notably dynamic factor models together with detailed worked examples from the behavioral sciences and special software for the analyses.

Table of Contents
