Chaos Data Analyzer

 

---

The program,Chaos Data Analyzer, is a research and teaching tool containing 14 tests for detecting hidden determinism in a seemingly random time series of up to 16,382 points provided by the user in an ASCII data file. Sample data files are included for model chaotic systems. When chaos is found, calculations such as the probability distribution, power spectrum, Lyapunov exponent, and various measures of the fractal dimension enable you to determine properties of the system underlying the behavior. The program can be used to make nonlinear predictions based on a novel technique involving singular value decomposition. The program is menu-driven, very easy to use, and even contains an automatic mode in which all the tests are performed in succession and the results are provided on a one-page summary.

Chaos Data Analyzer requires an IBM PC or compatible with at least 512K of memory. A math coprocessor is recommended (but not required) to speed some of the calculations. The program is available on 5.25 or 3.5" disk and includes a 62-page User's Manual. Chaos Data Analyzer is peer-reviewed software published by Physics Academic Software, a cooperative project of the American Institute of Physics, the American Physical Society, and the American Association of Physics Teachers.
