This book illustrated the complete mathematical background and other implementation concerns for a credit risk scorecards(the way a bank accesses the approval of any lending). Pretty impressive and only of its kind in the market for credit scorecard building, validation, calibration...with complete math backing

My comment on different aspects of the book:

On more technical aspect: I wish the book could have models on Loss-given-default model since it's also part of credit risk model...

On the style: The book is too concise on its maths. Wish to have more elaboration or references so that I can drill down its math.
