DESCRIPTION</div>
<bR>
<div>
Visual Recurrence Analysis (VRA) version 4.2 for Windows 95, 98, 2000,</div>
<div>
and NT is a software package for topological analysis, qualitative and</div>
<div>
quantitative assessment, and nonparametric prediction of nonlinear and</div>
<div>
chaotic time series.</div>
<bR>
<bR>
<div>
MAIN FEATURES</div>
<bR>
<div>
- Pattern and determinism recognition in the time series using</div>
<div>
&nbsp; recurrence plot, which is essentially a graphical representation of</div>
<div>
&nbsp; the correlation integral in such a way so that the temporal dependence</div>
<div>
&nbsp; in the system under study is preserved. </div>
<bR>
<div>
- Dynamic recurrence quantification analysis (RQA) for recurrence plots</div>
<div>
&nbsp; classification and characterization: analyze stationarity, periodicity,</div>
<div>
&nbsp; determinism, and complexity of the dynamical system as it evolves in</div>
<div>
&nbsp; time.</div>
<bR>
<div>
- Recurrence plots animation: see the dynamical system trajectories</div>
<div>
&nbsp; stretch and unfold in real time.</div>
<bR>
<div>
- Average Mutual Information, False Nearest Neighbors, and</div>
<div>
&nbsp; spatio-temporal entropy methods to determine the optimal values of</div>
<div>
&nbsp; embedding dimension and time delay for delayed coordinate embedding.</div>
<bR>
<div>
- Nonparametric modeling for nonlinear time series prediction. A wide</div>
<div>
&nbsp; variety of models and options is available, including nearest neighbor,</div>
<div>
&nbsp; locally constant, locally linear, locally weighted linear, kernel</div>
<div>
&nbsp; regression, and radial basis functions models.</div>
<bR>
<div>
- Importing time series stored in different file formats, including</div>
<div>
&nbsp; ASCII text, MS Excel, and sound (WAVE) formats.</div>
<bR>
<div>
- Sample data files, extended help, and references are provided. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</div>

INSTALLING VISUAL RECURRENCE ANALYSIS v4.2</div>
<bR>
<div>
Before you install Visual Recurrence Analysis v4.2, remove the previous</div>
<div>
version of VRA (if any) from your computer. See the next paragraph for</div>
<div>
the removal instructions. To install VRA v4.2 on your computer, download</div>
<div>
file vra4v2.zip from http://pweb.netcom.com/~eugenek/download.html</div>
<div>
and unzip it into a temporary folder. Then run setup.exe from there and</div>
<div>
follow the on-screen instructions.</div>
