Description of attractors and random fluctuations in psychotherapy time series

attractor computation on website

The FPE is a stochastic differential equation that models a time series of some variable x by a stochastic (diffusion) and a deterministic (drift) term (Haken, 2004). The application to psychology has been announced by Tschacher, Haken & Kyselo (2015) and is elaborated and discussed in the book Tschacher & Haken, 2019. The FPE algorithm on this website estimates, on the basis of a one-dimensional time series, the deterministic forces and the stochasticity, for each x contained in the time series. Thus, the underlying deterministic attractor landscape of fixed-point attractors of a time series can be approximated.
