Question 1

What is the primary advantage of an internally developed credit scoring model over relying solely on external credit scores?

Accepted Answer

Internal models can incorporate company-specific payment history, industry data, and tailored risk appetite

Answer

Internal models can be calibrated to the company's specific customer base, products, and risk tolerance, using proprietary payment data that external bureaus do not have.

Question 2

What does 'scorecard validation' refer to in credit scoring model development?

Accepted Answer

Testing the scoring model against holdout or out-of-sample data to assess its predictive accuracy

Answer

Scorecard validation involves applying the model to data not used in its development to confirm it predicts credit risk reliably and has not been overfitted.

Question 3

What is 'behavioral scoring' in the context of credit management?

Accepted Answer

Using an established customer's ongoing payment behavior and account activity to dynamically reassess creditworthiness

Answer

Behavioral scoring continuously monitors existing customers' actual payment patterns and account usage to update credit risk assessments and adjust credit limits over time.

Question 4

Which statistical technique is most commonly used to develop credit scoring models?

Accepted Answer

Logistic regression

Answer

Logistic regression is the industry standard for credit scoring because it models the probability of a binary outcome — default versus non-default — as a function of predictor variables.

Question 5

In credit scoring, the Gini coefficient is used to measure:

Accepted Answer

The discriminatory power of a scoring model to separate good accounts from bad accounts

Answer

In credit risk, the Gini coefficient (derived from the ROC curve) quantifies how well a model distinguishes between creditworthy and non-creditworthy obligors; higher values indicate better separation.
