Following Hemerik and Goeman (2018) , 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. authors: - family-names: Ningsih given-names: Tri Zahra email: trizahra10019@gmail.com - name: Aman - family-names: Nasrulloh given-names: Ahmad - family-names: Hastuti given-names: Hera email: herahastuti@fis.unp.ac.id - family-names: Putri given-names: Suci Kurnia repository: https://trizahra10019-spec.r-universe.dev repository-code: https://github.com/exactGMH-project/exactGMH commit: 052380a83b7a4a46bc100a911335debc472c682b url: https://github.com/exactGMH-project/exactGMH date-released: '2026-08-09' contact: - family-names: Ningsih given-names: Tri Zahra email: trizahra10019@gmail.com
