WebIf you reverse the axis of chart shown in the above section named "Gini Coefficient", you would get similar to the chart below. Here Gini = B / (A + B). Area of A + B is 0.5 so Gini = B / 0.5 which simplifies to Gini = 2*B. AUC = B + 0.5 which further simplifies to B = AUC - 0.5. Put this equation in Gini = 2*B.
