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