| Abstract: | A model is proposed which treats rankings given by a group of judges as representing regions in an isotonic space of dimensionalityr. Three possible criteria for estimating lower bound dimensionality are discussed: mutual boundary, cardinality, and the occurrence of transposition groups. Problems associated with each criterion are mentioned.Deceased. |
