 I approach modelling from a somewhat different perspective to most others, and there is relatively little space devoted to it.
 Modelling really deserves a book on its own, so I'd highly recommend that you read at least one of these three books:
 
--   *Statistical Modeling: A Fresh Approach* by Danny Kaplan, <http://project-mosaic-books.com/?page_id=13>.
+-   *Statistical Modeling: A Fresh Approach* by Danny Kaplan, <https://dtkaplan.github.io/SM2-bookdown/>.
     This book provides a gentle introduction to modelling, where you build your intuition, mathematical tools, and R skills in parallel.
     The book replaces a traditional "introduction to statistics" course, providing a curriculum that is up-to-date and relevant to data science.
