statsmodels.stats.oneway.f2_to_wellek¶

statsmodels.stats.oneway.f2_to_wellek(f2, n_groups)[source]¶

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
