Visual Recurrence Analysis version 4.2 Release Notes


DESCRIPTION

Visual Recurrence Analysis (VRA) version 4.2 for Windows 95, 98, 2000,
and NT is a software package for topological analysis, qualitative and
quantitative assessment, and nonparametric prediction of nonlinear and
chaotic time series.


MAIN FEATURES

- Pattern and determinism recognition in the time series using
  recurrence plot, which is essentially a graphical representation of
  the correlation integral in such a way so that the temporal dependence
  in the system under study is preserved. 

- Dynamic recurrence quantification analysis (RQA) for recurrence plots
  classification and characterization: analyze stationarity, periodicity,
  determinism, and complexity of the dynamical system as it evolves in
  time.

- Recurrence plots animation: see the dynamical system trajectories
  stretch and unfold in real time.

- Average Mutual Information, False Nearest Neighbors, and
  spatio-temporal entropy methods to determine the optimal values of
  embedding dimension and time delay for delayed coordinate embedding.

- Nonparametric modeling for nonlinear time series prediction. A wide
  variety of models and options is available, including nearest neighbor,
  locally constant, locally linear, locally weighted linear, kernel
  regression, and radial basis functions models.

- Importing time series stored in different file formats, including
  ASCII text, MS Excel, and sound (WAVE) formats.

- Sample data files, extended help, and references are provided.      	


INSTALLING VISUAL RECURRENCE ANALYSIS v4.2

Before you install Visual Recurrence Analysis v4.2, remove the previous
version of VRA (if any) from your computer. See the next paragraph for
the removal instructions. To install VRA v4.2 on your computer, download
file vra4v2.zip from http://pweb.netcom.com/~eugenek/download.html
