    en.wikipedia.org/wiki/Modular_arithmetic

    Fermat's little theorem: If p is prime and does not divide a, then a p−1 ≡ 1 (mod p). Euler's theorem: If a and m are coprime, then a φ(m) ≡ 1 (mod m), where φ is Euler's totient function. A simple consequence of Fermat's little theorem is that if p is prime, then a −1 ≡ a p2 (mod p) is the multiplicative inverse of 0 < a < p.

    As an example, if the two distributions do not overlap, say F is below G, then the PP plot will move from left to right along the bottom of the square – as z moves through the support of F, the cdf of F goes from 0 to 1, while the cdf of G stays at 0 – and then moves up the right side of the square – the cdf of F is now 1, as all points of F lie below all points of G, and now the cdf ...
