Bayesian stats outperforms p-values for RNG bias testing

One integral replaces infinite p-values in randomness tests

Deep Dive

Key Points
  • Uses likelihood ratios instead of p-values, integrating over all possible biases with a uniform prior
  • Closed-form solution derived for likelihood ratio of biased vs perfect RNG given count of ones
  • For n=1000, ratio strongly favors bias at extremes (e.g., 0 or 1000 heads) and neutral near 500 heads

Why It Matters

Bayesian hypothesis testing offers a principled alternative to p-values for RNG validation and beyond.
