Open Source statistical textbooks? There have been a few questions about statistical textbooks, such as the question Free statistical textbooks. However, I am looking for textbooks that are Open Source, for example, having an Creative Commons license. The reason is that in course material in other domains, you still want to include some text about basic statistics. In this case, it would be interesting to reuse existing material, instead of rewriting that material.
Therefore, what Open Source textbooks on statistics (and perhaps machine learning) are available?
 A: The "Statistics" book on wikibooks
A: OpenIntro Statistics is available via CC BY-SA. The LaTeX source code plus the R code to generate every figure in the textbook is also readily available in a single download.
OpenIntro's website also highlights several other freely available statistics textbooks at the beginner, intermediate, and advanced levels.
A: Street-Fighting Mathematics. The Art of Educated Guessing and Opportunistic Problem Solving by Sanjoy Mahajan from MIT. Available under a Creative Commons Noncommercial Share Alike license.
Available as a free download on the MIT Press website (but not from the author's website).
A: Statistical Analysis with the General Linear Model
It covers basic linear models (ANOVA, ANCOVA, multiple regression). I can tell by personal experience that it is really really good book to get into the general framework of linear models, which are very useful in many advanced approaches (e.g., hierarchical modeling).
A: R programming wiki book
A: Some googling found Statistics & Probability on CollegeOpenTextbooks.org. Still, be aware that most of CC-ed material is share-aliked (so you must also publish your work on CC) or at least attributed (so you must add info that certain part was copied and from whom). The same works with GFDL (both SA & A), it is even worse since in principle you should print it along with the document.
A: Collaborative Statistics is CC BY: http://cnx.org/content/col10522/latest/
A: Try IPSUR, Introduction to Probability and Statistics Using R by G. Jay Kerns. It's "free, in the GNU sense of the word". 
http://ipsur.r-forge.r-project.org/book/
It's definitely open source - on the download page you can download the LaTeX source or the lyx source used to generate this. 
A: Michael Lavine: Introduction to Statistical Thought, licensed under a Creative Commons Attribution-Noncommercial-Share Alike 3.0 United States License.
A: Multivariate statistics with R
A: Look at Statistics Topics ebook on Amazon by Mehta, and his free web log Statistics Ideas that has lecture slides.  Nearly free and better in some pedagogical topics, than the ones you cite on your list of resources.
