GRADE DISCRIMINANT FUNCTION IN TWO-CLASS PROBLEMS
M. Niewiadomska-Bugaj
W. Szczesny
Abstract: The so-called -level grade discriminant function is introduced and its properties
are investigated. In particular, its distributions in class and class serve to characterize
some natural ordering of discriminant models. Rules defined by comparing the value of a
chosen grade discriminant function with constant thresholds are presented as solutions of
some discriminant problems (forced and partial). The role of the ”sample based” counterparts
of the grade discriminant functions in inference based on ranks of discriminant scores is
mentioned.
