## Credit Risk Modeling
In this course, students learn how to develop credit risk models in the context of the Basel guidelines. The course provides a sound mix of both theoretical and technical insights, as well as practical implementation details. These are illustrated by several real-life case studies and exercises. În urma acestui curs, veți învăța să
- develop probability of default (PD), loss given default (LGD), and exposure at default (EAD) models
- validate, backtest, and benchmark credit risk models
- stress test credit risk models
- develop credit risk models for low default portfolios
- use new and advanced techniques for improved credit risk modeling.
