Effective interventions may not be limited to changing means, but instead may also include changes to how variables affect each...
This is an introduction to dynamical systems ideas. Dynamical systems are mathematical models of one or more constructs that change...
This chapter introduces one approach to describing constructs that consist of easily reversed, short–term changes — data that is often...
Methods for fitting the damped linear oscillator model using differential equation modeling can yield biased parameter estimates when applied to...
Historically, it has been easier to describe differences between groups of people, rather than describe the dynamic ways that people...
A wide variety of models can be understood in terms of the level, velocity, and acceleration of constructs: the zeroth,...
This essay reviews emerging trends in modeling repeated measures data. Three longitudinal models are discussed: panel model designs, growth curve...
The fitting of dynamical systems can be improved by estimating derivatives in a manner similar to that used to fit...
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...
