statsmodels.stats.oneway.wellek_to_f2

statsmodels.stats.oneway.wellek_to_f2(eps, n_groups)

Convert Wellek’s effect size (sqrt) to Cohen’s f-squared

This computes the following effect size :

f2 = 1 / n_groups * eps**2

Parameters:

• eps (float or ndarray) – Wellek’s effect size used in anova equivalence test

• n_groups (int) – Number of groups in oneway comparison

Returns:

f2

Return type:

effect size Cohen’s f-squared
