This paper focuses on multivariate logistic representations of paired and multiple comparisons models. Bock's (1975) logistic model is chosen as a common framework for extending the Bradley-Terry-Luce model, Luce's model of first choices, the Babington-Smith and the Pendergrass-Bradley ranking models to accommodate multiple responses. Relationships between the responses are constrained to vary as an additive function of the objects being compared. The methodology is exemplified by analyzing bivariate choice data from a questionnaire study.
