The correlational structure of judgments of grammatical coreference is examined using factor analysis and the results are used to identify the dimensions of grammatical variation in competent speakers of English. The dimensions that are discovered do not correspond to those typically discussed in generative linguistics but they can be explained very naturally by a model in which coreference is achieved through a process in which linguistic expressions are mapped onto a model of discourse.
