ABSTRACT
Dynamical systems analysis is characterized by an interest in understanding the change and variability of one or more constructs. While many methods in statistics are focused on the analysis of mean differences, the questions posed in the dynamical systems literature are often focused on differences in the amount and type of variability that occurs in a variable of interest and what variable or variables constitute a regulatory mechanism. In many health-related constructs, the distinctive features may not be in mean differences between groups of individuals but rather in the fluctuations that comprise intraindividual variability.
