WebbDetails. Shannon or Shannon–Weaver (or Shannon–Wiener) index is defined as H' = -\sum_i p_i \log_{b} p_i, where p_i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference).. Both variants of Simpson's index are …
