Abstract
Fisher’s two-group discriminant function has been generalized in two different ways for the case of three or more groups. Both generalizations have been called discriminant functions, leading to confusion in the literature. A reasonable nomenclature is canonical discriminant functions and classification functions. The precise functional relation between the two functions is derived, and the interpretation of the two functions is discussed. An illustrative example is provided.
