The relationships between the similarity thresholds s₁ and s₂, and the probabilities p₁ and p₂, for n = 100, k = 5. Given a probability, e.g. $p_1=p_2=0.25$ shown by the horizontal gray line, the OMH method can distinguish between similarities below s₂ (below left vertical gray line) and from similarities above s₁ (above the right vertical gray line). The functions are defined at discrete points, when ns is integral, represented by the circles and squares
