What is Gini coefficient in machine learning?
The Gini Coefficient or Gini Index measures the inequality among the values of a variable. Higher the value of an index, more dispersed is the data. Alternatively, the Gini coefficient can also be calculated as the half of the relative mean absolute difference.
How is Gini model calculated?
The Gini coefficient is equal to the area below the line of perfect equality (0.5 by definition) minus the area below the Lorenz curve, divided by the area below the line of perfect equality. In other words, it is double the area between the Lorenz curve and the line of perfect equality.
What is Gini in credit scoring?
When applied to credit scoring, the gini coefficient compares the distribution across the credit score range of consumers who defaulted on their loans (ie., those who went 90 days or more past due) to that of consumers who did not default on their loans.
