Visual Recurrence Analysis (VRA) for
Windows 95, 98 and NT is a software package for
topological analysis, qualitative and quantitative
assessment, and nonparametric prediction of nonlinear/chaotic
time series. It can detect hidden patterns and
determinism in time series using a graphical device known
as the recurrence plot. VRA
first expands a given one-dimensional time series into a
higher-dimensional space, in which the dynamics of the
underlying generator takes place. VRA then constructs a
recurrence plot, which is essentially a graphical
representation of the correlation integral in such a way
so that the time dependence in the system under study is
preserved. Examples: Lorenz Attractor |
The following data examples are also included with VRA: Far-Infrared-Laser
in a chaotic state (5000 data points); |
