statsmodels.stats.oneway.f2_to_wellek

statsmodels.stats.oneway.f2_to_wellek(f2, n_groups)

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

This computes the following effect size :

eps = sqrt(n_groups * f2)

Parameters:

• f2 (float or ndarray) – Effect size Cohen’s f-squared

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

Returns:

eps – Wellek’s effect size used in anova equivalence test

Return type:

float or ndarray
