Abstract:
|
In practical settings when judges rank items, not only covariates for the judges can help explain their rankings but also item covariates and the interplay between the judge and item covariates. This talk will extend a Plackett-Luce model by specifying model parameters as functions of the judge and item covariates and present an application of the model to a data set from a FIFA Best Player award.
