pub fn mcnemar(b: u64, c: u64) -> Option<NonparametricResult>Expand description
McNemar’s test for two paired binary classifiers: b is the count where A is
right and B wrong, c where A is wrong and B right (the discordant cells of the
2×2 agreement table). Uses the continuity-corrected statistic
(|b−c|−1)²/(b+c) ~ χ²₁. None if b + c == 0 (no discordance).
