I was looking for some references and examples in the scope of the “Regression Models” course on Coursera. Something structured that could bridge the gaps in my R knowledge (and they are many) and something that could provide me with a list of case studies. I have already bought a book on this, it is “Statistiques avec R”, ISBN 978-2-7535-1992-3. This book costed me about 20 EUR and it is providing a rather good central part with a series of cases that are explored in a structured and clear way. However, I needed more. And I needed a bit more on Ggplot. And I needed a bit more about Inferential Statistics (although I passed the Coursera course with flying colours, I do not yet feel confident about a few of the subjects treated there). So, googling back and forth, I found a few treasures:

- The R Programming language section on freecomputerbooks.com
- The mathematics and statistics section on bookboon.com
- The R Cookbook web site
- The study journal “Statistics in R”, with free PDF

I have already mentioned in the previous post bookbon.com. The “Statistics in R” is a bit dated (2007), so all the installation chapters and the graphical interface references to rcmdr can be skipped. The rest is still good. The section on freecomputerbooks.com is packed with more than 15 references. I did not have yet the time to look at them, but they look promising. More on that later.
