TISEAN – dealing with chaotic systems

The TISEAN software package is a collection of command line utilities addressing
methods of nonlinear time series analysis. These are based on the paradigm of deterministic chaos. A variety of algorithms for data representation, prediction, noise reduction, dimension and Lyapunov estimation, and nonlinearity testing are discussed with particular emphasis on issues of implementation and choice of parameters. Source code in C and Fortran is publicly available. Support for GnuPlot is provided.
