One statistician (not much of a sample size, is it?) - or rather, one economist in training, with some background in statistics - argues that the odds for the classical part of the upcoming Carlsen-Anand match are very heavily in the challenger's favor. On his (Matthew Wilson's) most generous interpretation, Carlsen has a 77.2% chance of winning the match before the tiebreaks, Anand a mere 10.3% chance. Have a look. (For comments on his argument, see here. If you're interested in his discussion of previous championship matches, then this is the article for you.)
