Recurrence quantification analysis as an empirical test to distinguish relatively short deterministic versus random number series

A simple data analysis strategy based on the scoring of recurrences, allowe d us to distinguish relatively short runs of (i) a chaotic system (logistic map), (ii) transcendental numbers (pi). (iii) pseudo-random numbers, and ( iv) physical random numbers (atmospheric noise). Beside the theoretical imp lications of distinguishing transcendental and pseudo-random numbers from p hysical noise, these results suggest a test (C) 2000 published by Elsevier Science B.V.
