First of all, the link to the errata form in this page
does not work.
About the error to be corrected, in the book on page 82, second paragraph, there is a parenthesis
( Note that the discussion of quality …. in the next secion may clarify this issue).
That discussion is not after, but before as of page 68
Thank you for bringing this to our attention!
I will submit your errata request directly, and it will be added to our errata list upon editorial approval.
