What is the formula of Gini?
What is the formula of Gini?
The Gini coefficient can be calculated using the formula: Gini Coefficient = A / (A + B), where A is the area above the Lorenz Curve and B is the area below the Lorenz Curve.
How do you read Gini?
The Gini index is a measure of the distribution of income across a population. A higher Gini index indicates greater inequality, with high-income individuals receiving much larger percentages of the total income of the population.

What is the difference between Gini Index and Gini coefficient?
The Gini coefficient is a measure of inequality of a distribution. The Gini index is the Gini coefficient expressed as a percentage, and is equal to the Gini coefficient multiplied by 100. (The Gini coefficient is equal to half of the relative mean difference.)
Is the Gini coefficient reliable?
Its results are also sensitive to outliers—a few very wealthy or very poor individuals can change the statistic significantly, even in a large sample. Cowell says that the Gini coefficient should not be used as the sole measure of economic inequality.
What is Gini coefficient in logistic regression?
The Gini coefficient is defined as the ratio between the area within the model curve and the random model line (A) and the area between the perfect model curve and the random model line (A+B).
What is Gini and KS?
Gini and AUROC are practically the same thing; one can be calculated simply from the other, and both measure the overall effectiveness of a model. By contrast, the KS statistic provides the best discrimination at a particular point in the Empirical Cumulative Distribution Function (ECDF).
