TISEAN is free
  a software project for the analysis of time series with methods based on the theory of nonlinear deterministic dynamical systems, or chaos theory, if you prefer. The software has grown out of the work of our groups during the last few years and was put into distributable form for the Winter School on Nonlinear Time Series Analysis (TISEAN 98), held in Dresden, 11-21 Feb 1998. Some of the routines are built around the programs given in

  > H. Kantz and T. Schreiber, ``Nonlinear Time Series Analysis'', Cambridge University Press, Cambridge (1997).

TISEAN disclaimer
  This software is given WITHOUT ANY WARRANTY; without even an implied statement of merchantability or fitness for a particular purpose. If you decide to use these programs, you do so entirely AT YOUR OWN RISK.

TISEAN distribution
  is in source form (some code in C, some in FORTRAN) including the full documentation. Also, executables for some archtectures are available. Please consult the download page for available formats. You are very welcome to port the programs to other platforms or write interfaces to other software. Let us know of any success!

TISEAN installation
  The software can be compiled and installed using some reasonable version of make, a C compiler, and a FORTRAN compiler. The gcc / g77 family will do fine. If you lack one of the compilers, part of the package may still compile and work. It would be a pity, though, for the other part.

TISEAN updates
  The range of programs is constantly growing and improving. For the latest version, check http://www.mpipks-dresden.mpg.de/~tisean. We are doing our best to remove bugs and straighten things but we are also working on additional material to be included in later releases. If you want to keep up-to-date about bug fixes and updates, you are welcome to join our mailing list --- no junk - subsrcribe now ! --- by sending e-mail (no subject, text: subscribe tisean) to mdtisean.

TIme SEries ANalysis
  remains a difficult business, in particular the nonlinear kind. You may be assured that when treating the programs as a black box, you are certain to get nonsensical results. Even if you know what you are doing, output produced by the programs has to be interpreted very carefully and can often not be taken as it is. Now that you are warned, go ahead and have fun!
