This is the first of a two big red tomes: each is about 3 inches thick,
However, I should extend a word of warning about this text: Be prepared for the sight of at least some mixture of statistical-calculus and other "math". Then again, this isn't quite the scary stuff that they tortured you with during your math classes (maybe since I know I won't need to be sitting a test on this and need to actually be able to perform some of the symbolic manipulations needed ;) Haha.
In a followup twist, it turns out that the author of one of the latter sections has even posted a PDF of a relevant chapter online - the one I'd just managed to randomly flip to a particularly juicy part of just before having to head off. After taking a more detailed look at it this afternoon, I have to say that I'm impressed - and very glad that I found this absolute gem!
