This is an introduction to dynamical systems ideas. Dynamical systems are mathematical models of one or more constructs that change...
Brief summary of post contents Generalized Local Linear Approximation is a generalization of local linear approximation of derivatives (LLA, Boker...
Rapid Cycling Bipolar Disorder outpatients completed twice-daily mood self-ratings for 3 consecutive months. These ratings were matched with local measurements...
A wide variety of models can be understood in terms of the level, velocity, and acceleration of constructs: the zeroth,...
This article describes a model based on a reservoir. This model might be useful for constructs (e.g., stress), where events...
This essay reviews emerging trends in modeling repeated measures data. Three longitudinal models are discussed: panel model designs, growth curve...
Methods for fitting the damped linear oscillator model using differential equation modeling can yield biased parameter estimates when applied to...
Using embedded and observed data matrices, a statistical approach to differential equation modeling is presented. This approach appears robust to...
Two studies examined the role short-term changes in adult attachment and mindfulness play in depression and general anxiety.
Daily data from the NDHWB (n = 783; age range 37–90) were analyzed to produce ‘dynamic characteristic’ estimates of stress...
