Minor typos
 
The book is a pleasure to read. The text, graphics, and math equations are cleanly presented and integrated.

There is a minor typo on page 84. The third equation has a period at the end, when it should have a comma.

Very keen observation! Thank you for noticing it.

Proposed errata in my printing (1.10? purchased Oct. 2014):
  • Exercise 3.12 last line: "elipses" -> "ellipses"
  • Problems 3.4-3.5: "E_n" -> "\text{e}_n" for consistency with p. 98
  • Problem 3.6 initial description, last line: "most mathematics software have" -> "most mathematics software packages will have" [software is an uncountable noun and hence not considered plural - http://en.wiktionary.org/wiki/software]
  • Problem 3.11 (b), last part of the trace: "X^T (X^T X)^{-1}" -> "X (X^T X)^{-1}" [extra transpose; matrix multiplication dimension mismatch]
  • Problem 3.13, bottom of p. 113: "More generally, The" -> "More generally, the" [capitalization]
  • Problem 3.14: "the bias and variance" -> "the bias and var", and "What is the variance?" -> "What is the var?" [for consistency with Chapter 2, and to avoid confusion with the variance of the iid noise random variables]

We appreciate these remarks!

Re: Minor typos
 
To add to this: there seems to be an overall 1/N missing in the formula for E_{in} in problem 3.9. (I also do not seem to need positive definiteness of X^T X.)
