How does this compare to, say "Introduction to Statistical Learning" and "Elements of Statistical Learning" by Trevor et al? As I understand, the former is also supposed to be a concise introduction to statistical concepts while the latter offers a more rigorous treatment. Where does this book fall in between?
This book is not between ISL and ESL. All of Statistics is an introductory course (and has a much wider scope, including advanced topics) while even the watered-down ISL assumes that the reader knows already a bit of statistics.
