for the book The MDL Principle" by Peter D. Grünwald

- Chapter 17: There is a serious mistake in the discussion of
*mixability*on page 577, before and beneath Equation (17.27). Here is a better version of the paragraph (this erratum has already been fixed in the version of Chapter 17 that is available as a sample chapter on the web, and in the second printing that will appear March 2009). - Chapter 3: There is a mistake in the calculation of codelengths for quasi-uniform description methods (page 90), which leads to a mistake in the development of the integer-codelength version of the universal code for the integers (page 100). Here is a better version of page 90 and here is a better version of page 100. This erratum has also mostly been fixed in the second printing of March 2009, although in that printing, there is still a small mistake in eq. (3.5) on page 90.
