Following Hemerik and Goeman (2018) <doi:10.1007/s11749-017-0571-1>, the permutation p-value is exact at the nominal level rather than an approximation, even for a finite number of permutations. This makes the test valid for small samples (fewer than 200 examinees per group), a condition common in classroom-, program-, and institution-level assessment where existing exact-inference options in other software are restricted to dichotomous items only. An optional Benjamini-Hochberg or Bonferroni correction addresses multiple comparisons when screening many items at once.https://github.com/r-universe/trizahra10019-spec/actions/runs/37915953241Sun, 09 Aug 2026 08:10:06 GMTexactGMH0.1.0successhttps://trizahra10019-spec.r-universe.devhttps://github.com/cran/exactGMH
