Most methods in statistics are focused on the analysis of mean differences. Mean–difference questions, however, represent only a narrow range...
This article describes a model based on a reservoir. This model might be useful for constructs (e.g., stress), where events...
This chapter introduces one approach to describing constructs that consist of easily reversed, short–term changes — data that is often...
Many applied statistical problems address how change two variables are related. In this chapter derivatives are presented as a language...
Effective interventions may not be limited to changing means, but instead may also include changes to how variables affect each...
Intraindividual measures, such as intraindividual standard deviation or coefficient of variation, are incomplete representations variability. Studying variability can be made...
Daily data from the NDHWB (n = 783; age range 37–90) were analyzed to produce ‘dynamic characteristic’ estimates of stress...
A wide variety of models can be understood in terms of the level, velocity, and acceleration of constructs: the zeroth,...
Stochastic differential equation (SDE) models are a promising method for modeling intraindividual change and variability. This method uses structural equation...
Historically, it has been easier to describe differences between groups of people, rather than describe the dynamic ways that people...
