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...
Daily data from the NDHWB (n = 783; age range 37–90) were analyzed to produce ‘dynamic characteristic’ estimates of stress...
This essay reviews emerging trends in modeling repeated measures data. Three longitudinal models are discussed: panel model designs, growth curve...
Most methods in statistics are focused on the analysis of mean differences. Mean–difference questions, however, represent only a narrow range...
Rapid Cycling Bipolar Disorder outpatients completed twice-daily mood self-ratings for 3 consecutive months. These ratings were matched with local measurements...
Effective interventions may not be limited to changing means, but instead may also include changes to how variables affect each...
The fitting of dynamical systems can be improved by estimating derivatives in a manner similar to that used to fit...
