What this book is trying to do
The goal is not to turn every reader into a theorist or trader. It is to explain why an idea appeared, what the model claims, which assumptions make it work, and what can go wrong in actual implementation. A little mathematics and a few reproducible R examples will support the intuition rather than replace it.
