A First Course in Model Validation and Model Risk Management explains in step-by-step, practical terms how mathematical models owned by financial institutions are essential to their public (sales, trading, risk management, and internal audit) and private (merger and acquisition, and IPO) activities. Like a diverse fleet of cars maintained by a rental car location, a bank must make sure customers can “drive” any of its models in seeking a profit or hedge in a specific financial product. The book is divided into three sections on conventional pricing and risk models, including risk-neutral and historical measures. Chapters consider modeling basics, marked-to-market asset classes, market risk, credit risk, portfolio risk, operational risk, capital model risk, and financial crime, along with machine learning, AI, and Python specific modeling and risk assessment techniques. Problems sets, video examples, sample Python code, and an instructor manual are offered on companion and instructor sites to support learning and provide an opportunity to put concepts into practice. A refresher in statistics and an abbreviation glossary are included across two appendices.

In 2017 an intense fundraising campaign ensured that what came to be known as 'the Galloway Hoard' was saved for the nation. Since then work has been ongoing to preserve and understand it. Over 5kg of silver bullion, many unique and enigmatic gold objects, the rare preservation of textiles and an unusual range of other materials, make the Hoard the richest collection of Viking-age objects every found in Britain and Ireland. Dr Martin Goldberg and Dr Mary Davis provide the first full description of the Hoard and place the find in a wider historical and geographical context.

As well as showcasing beautiful objects from the collections of National Museums Scotland, this book, building on the Glenmorangie Research Project, gives fresh insights into the emergence of the early medieval kingdoms of Scotland.
