WebMcIntosh's Index is based on a geometric model: u = (Ni2) e.g., N=7; N1=3, N2=4 u = (Ni2) = (32+ 42) = 5 = length of vector from origin e.g., N=10; N1=2, N2=3, N3=5 u = (Ni2) = (22+ 32+ 52) = 6.1644 From this, McIntosh defined an equitability index: M = N - u An obvious disadvantage is that M = f(N); however, M can be normalized (Peet 1974):
