Problems 3.4-3.5: "" -> " $\text{e}_n$ " 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!
