Gives you a good general sense of different statistical techniques that could be applied to trading and investing. It will give you a background and stimulates ideas that can augment your trading and investment experience. More concrete and granular examples that could get into the essence of application for profit are not supplied. I was unhappy the questions at the end of each chapter did not have an answer key. While they were created to make you think they did not supply the ready material for you to understand and apply the material. Like any more sophisticated material its meaning becomes better understood the more times you review it. Similarly with this book. It is really a stepping stone not an end all.
