Talk:Similarity score

Untitled
Nowhere does the article say HOW a similarity score is actually defined. This would seem to be of utmost interest. There are quite clearly numerous basic scoring systems (e.g. KUBIAC of the Football Outsiders, as mentioned in the article), but is the SIMILARITY SCORE calculated in the same manner regardless of scoring system? And HOW is such a similarity score calculated. Fyo 23:41, 18 August 2007 (UTC)
