a lil repo to play around with models, algorithms, and technologies for paired comparisons stuff like testing the speed of different implementations of Bradley-Terry and Rao Kupper models
For binary paired comparison models data is presented as matchups (np.int32, [n,2])
containing winner and loser indices.
For ternary data it's matchups (np.int32, [n,2])
(order arbitrary) and outcomes (np.float32, [n,])
taking values 1.0, 0.5, 0.0 representing win, draw, and loss for the first indexed competitor
