A First Course in Model Validation and Model Risk Management
Autor Jonathan Schachter, Martin Goldberg, Chandrakant Maheshwarien Limba Engleză Paperback – 27 mar 2026
To support course use and practical applications, the text provides examples in Python throughout, as well as an appendix containing homework problems for all chapters, further supported by an ftp site for data and sample code. Additional appendices cover global model risk management, and a refresher in statistics.
- Offers practical concepts for learning model validation and model risk management
- Explains how to use Python-based models to assess and manage model risk
- Covers the US gold standard of model risk, "Federal Reserve Board SR 11-7", including testing inputs, testing outputs, benchmarking, outcomes analysis, third party models, and compensating controls
- Discusses model governance, including model inventory , risk ratings, and the three lines of defense
- Provides Instructor Manuals for qualified instructors via https://www.educate.elsevier.com/book/details/9780443337468
