CompareMeans.summary(use_t=True, alpha=0.05, usevar='pooled', value=0)

summarize the results of the hypothesis test

Parameters:

use_tbool, optional

if use_t is True, then t test results are returned if use_t is False, then z test results are returned

alphafloat, optional

significance level for the confidence interval, coverage is 1-alpha

usevar{“pooled”, “unequal”}, optional

If pooled, then the standard deviation of the samples is assumed to be the same. If unequal, then the variance of Welch ttest will be used, and the degrees of freedom are those of Satterthwaite if use_t is True.

valuefloat, optional

difference between the means under the Null hypothesis.

Returns:

smrySimpleTable

Summary table of the hypothesis test results.
