- statsmodels.stats.oneway._power_equivalence_oneway_emp(f_stat, n_groups, nobs, eps, df, alpha=0.05)[source]¶
Empirical power of oneway equivalence test
This only returns post-hoc, empirical power.
Warning: eps is currently effect size margin as defined as in Wellek, and not the signal to noise ratio (Cohen’s f family).
F-statistic from oneway anova, used to compute empirical effect size
Number of groups in oneway comparison.
Array of number of observations in groups.
Equivalence margin in terms of effect size given by Wellek’s psi.
Degrees of freedom for F distribution.
Significance level for the hypothesis test.
Ex-post, post-hoc or empirical power at f-statistic of the equivalence test.
