I wanted to know how a academic stuff (papers, articles, books and so on) are written. I also wanted to rigirously learn Probability and Statistics. So, I thought it would be a fun and very educational project to write an amateur book. I might also translate this book to my native language (azerbaijani) and publish it, since there are no such sources in azerbaijani.
You can use the book as review material. Remember that I am not a professor with years of teaching experience. I am just a student that has interest in math and programming. So, be warned.
You can find my LaTeX configuration in the file config.sty. It contains the visual settings of the book. It is very well documented (I think) and you can use the things you like on your projects and books.
In diagrams folder, you can find the source code of the illustrations. I am planning to make the diagrams after I finish the core of the book.
