WebbFigure 1 – Simpson’s Diversity Index Figure 1 shows the D and 1/D indices. Cell B7 contains the formula =SUMSQ (B5:F5) and cell E7 contains the formula =SUMPRODUCT (B4:F4,B4:F4-1)/ (G4* (G4-1)). Note that for a large population, the maximum value of D is 1/k, and so the maximum value of 1/D is k. WebbDetails. S I D I = 1 − ∑ i = 1 m P i 2. where P i is the proportion of class i and m is the number of classes. SIDI is a 'Diversity metric'. It is widely used in biodiversity and ecology. It is less sensitive to rare class types than lsm_l_shdi. It can be interpreted as the probability that two randomly selected cells belong to the same class.
