CompareMeans.ztost_ind(low, upp, usevar='pooled') [source]

test of equivalence for two independent samples, based on z-test

  • upp (low,) – equivalence interval low < m1 - m2 < upp
  • usevar (string, 'pooled' or 'unequal') – If pooled, then the standard deviation of the samples is assumed to be the same. If unequal, then Welsh ttest with Satterthwait degrees of freedom is used
  • pvalue (float) – pvalue of the non-equivalence test
  • t1, pv1 (tuple of floats) – test statistic and pvalue for lower threshold test
  • t2, pv2 (tuple of floats) – test statistic and pvalue for upper threshold test
