Webbv are closely related with diversity indices, R with the Rosenbluth diversity index B, and v with the Gini-Simp-son index D2,, (1). (2) Equation (1) will be employed in the sequel to define a proper multivariate extension of index D2. The relevant partial order in the univariate measure-ment of evenness is the Lorenz order, which is closely re- Webbwhere N is the total sample size, S is the total number of types described (total number of species), n i is the n-th type and p i is the frequency n i /N.According to the first formula, the Simpson's index can assume values from 0 to 1. When comparing two typing methods, to see which is the more discriminatory, one needs to compare the 95% Confidence …
