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).

The Shannon index has been a popular diversity index in the ecological literature, where it is also known as Shannon's diversity index, Shannon–Wiener index, and (erroneously) Shannon–Weaver index. The measure was originally proposed by Claude Shannon in 1948 to quantify the entropy (hence Shannon entropy, related to Shannon information content) in strings of text. The idea is that the more letters there are, and the closer their proportional abundances in the string of inter…
