The original version of the book was inadvertently published with an error in the numbering of citations and the same has been corrected throughout the book.

In chapter 3, a formula on page 94 was corrected to read as: v 1 = n 1 − 1 and v 2 = n 2 − 1

In chapter 5, a formula on page 168 was corrected to read as: σ 2 1,2 = 0.5 ∗ \( \raisebox{1ex}{$2$}\!\left/ \!\raisebox{-1ex}{$3$}\right. \) = 0.083
