Orbital Decomposition v 1.2 (by A. F. Peressini & S. J. Guastello) is now available for free downloads. ORBDE, which based on principles of symbolic dynamics, identifies recurring patterns of events in categorically-defined data. The analysis finds the optimal length of patterns, and lists the recurring patterns at that length. The final statistics include the string length, topological entropy, the (largest) Lyapunov exponent, fractal dimension, Shannon entropy, and a chi-square test for goodness of fit.
