The two lower limits of the expected ratio, ω, of agreement between two independent and equivalent judges in the k-group rational classification were established: one (L_0) for the non-negative prior distribution, r_1, r_2, …, r_k, for k groups (k≥2), and the other (L_3) for the positive priors, r_1, r_2, …, r_k (k≥3), where L_0≤L_3 when k≥3. The rational classification is such that its expected discriminability, if any, is never exceeded, under the same condition, by that of a classification by random assignment, or a random classification. Thus the k-group rational classification becomes equivalent to Formula(6).
