This is to announce that version 3.0 of Visual Recurrence
Analysis (VRA) for Windows 95, 98 and NT has been released.
VRA is a free software for topological analysis and qualitative
assessment of (chaotic) time series. It can detect hidden patterns
and determinism in time series using graphical device known as
the Recurrence Plot (RP). Before a RP is constructed, VRA expands
a given one-dimensional time series into a higher-dimensional
space, in which the dynamic of the underlying generator takes
place. This is done using a technique called "delayed coordinate
embedding", which recreates a phase space portrait of the dynamical
system under study from a single data series.VRA is very fast and
highly interactive. Extensive online help is provided. Many qualitative
and quantitative analysis tools have been added.
VRA version 3.0 remains free provided that you use it for educational/
academic/research purposes.
I welcome any questions and suggestions you may have regarding
VRA software and its use. Download VRA from
