Effect size package

Python package to calculate affect sizes (Cohen's δ, Hedge's g, Cliff's δ and Vargha-Delaney's A)

At the moment, only Cliff's δ is implemented. The other effect sizes will be added soon.

Usage

from effect_size_analysis.cliff_delta import cliff_delta
from numpy.random import rand

x: ndarray = rand(100)
y: ndarray = rand(100)
cliff_delta(s1=x,s2=y,alpha=0.05,accurate_ci=True)

(0.0136, (-0.1455859031658134, 0.17209949612394954))

The first value is the delta value, while the second tuple represents the confidence interval.
