Testing the predictive power: A comparative study of current default probability validation tests
作者:
Highlights:
• Probability of default (PD) validation tests are compared via a simulation study.
• Several tests possess only a limited power to detect PD’s which are too low.
• For cyclical portfolios the significance level of a test should be increased.
