Summary of the NIST test suite results. (a), (c) The minimum proportion pass rate of the 10−2 confidence interval for each statistical test, with exception of the random excursion/variant test, is approximately 0.96 for a sample size of 100 binary sequences with a bitstream length of 91K and 1M, the random excursion/variant minimum pass rate is 0.944 as indicated with the red vertical lines. For the tests with multiple outcomes like the non-overlapping template (NOT) the proportion area is averaged. (b), (d) To ensure the distribution of P-values is uniform, a chi-square test was applied to determine a P-valueT corresponding to the Goodness-of-Fit distributional Test on the p-values obtained for each test, with \(\text{PvalueT} = \Gamma (9/2, \chi 2/2)\) for each test and its subtests is calculated. For all test the \(\text{PvalueT} > 10^{-4}\) (sequence can be considered uniformly distributed)
