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

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

low, uppfloat

equivalence interval low < m1 - m2 < upp

usevarstr, ‘pooled’ or ‘unequal’

If pooled, then the standard deviation of the samples is assumed to be the same. If unequal, then Welch ttest with Satterthwait degrees of freedom is used


pvalue of the non-equivalence test

t1, pv1tuple of floats

test statistic and pvalue for lower threshold test

t2, pv2tuple of floats

test statistic and pvalue for upper threshold test
