If you are looking for my textbook
here it is for free in the Open Educational Resource Commons.
Writing for Statistics and Data Science is given out under the Creative
Commons 3.0 - Attribution license. That means you and anyone else has
the right to copy it, change it, even sell your version of it, as long
as credit for the original continues to be attributed to me. In short,
it's open source, have fun.
There were a few chapters that I didn't include because they were either too niche or too prone to becoming obsolete. I'll be posting them here on the blog, with links being added in this post as those chapters go up. Details after the break.
