UPDATE: LATE SEPTEMBER 2018. Due to unexpectedly heavy demand for *Statistical Modeling: A Fresh Approach*, we are currently out of stock of the print version. We expect to restock by early October. If you order now we will ship the book when we have it back in stock. Or, if you need the book immediately, you might prefer to use the Kindle version available here on Amazon.
