This site is devoted to the prediction of the outcomes of games played with an oval
ball. So far the site provides odds on teams competing in the
Super 15 rugby union
competition and the Australian Football League.
The method of prediction follows a well worn methodological path. Teams are
rated on the basis
of their past performances. These team ratings are then employed to predict the margins of
the upcoming round of matches. A team's ratings at any point in time is influenced by
a number factors. These are:
long-term
-
past scoring performance (over two years)
-
short-term scoring performance (over the last six weeks or so)
-
home ground advantage
-
travel burden (over time zones)
