smaa.cw {smaa} | R Documentation |
Calculate SMAA central weights from sampled rankings and the corresponding weights.
smaa.cw(ranks, pref)
ranks |
An N * m array of sampled rankings, where N is the number of SMAA iterations and m is the number of alternatives. |
pref |
An N * n array of sampled rankings, where N is the number of SMAA iterations and n is the number of alternatives. |
An m * n matrix of central weights, where each row corresponds to an
alternative and each column to a criterion.
The number of SMAA iterations is stored in attr(x, "smaa.N")
.
The value is given class smaa.cw
, use unclass(x)
to treat it as a regular matrix.
