sushi.RdDataset from the preflib website, discussing sushi preferences.
data(sushi)Sushi preference dataset.
Object sushi_table is a database of sushi preferences;
each row is a judge and the rows are rank vectors of the different
sushi types.
Object sushi is a likelihood function at the estimated
value of lambda
Object sushi_maxp is the maximum likelihood estimate for
the Bradley-Terry strengths of the sushis, at the estimate for lambda.
sushi_eq_classes is a named vector giving the
equivalences classes of sushi. Class 1 is tuna, class 2 is everything
else.
These objects can be generated by running script inst/sushi.Rmd,
which includes some further discussion and technical documentation and
creates file sushi.rda which resides in the data/
directory.
