| Abstract: | In the analysis of paired comparison data concerning European universities and students' characteristics, it is demonstrated how to incorporate subject-specific information into Bradley-Terry-type models. It is shown that preferences for universities and therefore university rankings are dramatically different for different groups of students. a log-linear representation of a generalized Bradley-Terry model is specified which allows simultaneous modelling of subject- and object -specific covariaties and interactions between them. |
