Table 4. NIST test suite results.
The minimum pass rate for each statistical test with the exception of the random excursion (variant) test is approximately = 980 for a sample size = 1,000 binary sequences. The minimum pass rate for the random excursion (variant) test is approximately = 642 for a sample size = 657 binary sequences.
