The program Chaos Data Analyzer: Pro is a research and teaching tool containing nineteen tests for detecting hidden determinism in a seemingly random time series of up to 32,000 points provided by the user in an ASCII data file. Forty-four sample data files are included for model chaotic and real-world 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: Pro is a DOS program that runs under older versions of Windows or using the freeware DOSBox program for Windows Vista and later. Until 2011 the program was distributed by Physics Academic Software for $300 but is no longer available from them. However, the current version of CDA:Pro without written documentation or technical support can be ordered directly from the author for $150 (US) by check or money order and will be delivered electronically as a ZIP file usually within 24 hours of receipt of payment. 

Note: The current version of CDA:Pro is 2.1.
