-
CompareMeans.ztost_ind(low, upp, usevar=
'pooled')[source]
test of equivalence for two independent samples, based on z-test
- Parameters:
- low, upp
float equivalence interval low < m1 - m2 < upp
- usevar
str, ‘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
- Returns:
- 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
