Trueskill: Apply Trueskill to Tournament Data
Description
Trueskill function to be applied to tournament data in dataframe format.
Data is required to be in long format with two rows for
each match, one with player 1 first and one with player 2
first.
Matches should be sorted such that the second copy
of the match appears in the second half of the dataframe.
The package currently only supports the trueskill
algorithm with one player per team. Should this not match
the data you are interested, a function could be written from
AdjustPlayers, Player and Gaussian, and SetParameters.
An example is provided at https://gist.github.com/bhoung/5596282
(runtime is approx 50 secs).
