Calculate SMAA pair-wise winning indices from sampled rankings.
smaa.pwi(ranks)
ranks |
An N * m array of sampled rankings, where N is the number of SMAA iterations and m is the number of alternatives. |
An m * m matrix of pair-wise winning indices. The index at (i, j) describes the share of samples for which alternative i has a better (lower) rank than alternative j.
