Back to Search-quality version diff: v1.1.0 → v1.2.0

Paired Wilcoxon signed-rank on per-query RR (B vs A):

- N_nonzero = 22
- W+ = 251.50, W− = 1.50
- Two-sided p = 0.000049
- One-sided p (v1.2.0 > v1.1.0) = 0.000025

McNemar on rank-1 outcome:

| v1.2.0 rank-1 | v1.2.0 not rank-1
--- | --- | ---
v1.1.0 rank-1 | 26 (concordant +) | 0 (regression)
v1.1.0 not rank-1 | 20 (improvement) | 4 (concordant −)

- Discordant pairs: b = 0, c = 20
- McNemar exact (binomial), two-sided p = 0.000002
