[EM] Statistical pairwise method

[Kristofer Munsterhjelm]

A few days ago, I happened upon this page:

http://www.anishathalye.com/2015/03/07/designing-a-better-judging-system/

which seems to describe a pairwise method that's based on maximizing the
MLE of a model where a voter samples some preference for X and for Y on
two Gaussians (with unknown means) and votes X>Y if his sample for X is
greater than his sample for Y.

Is this Condorcet? It might well be (because of the Condorcet jury
theorem). In any case, it's an interesting approach, and reminds me of
Peter Zbornik asking some years ago if it'd be possible to model voter
decisions as uncertain on some statistical basis and take that into account.
