Webb31 jan. 2024 · The Shannon diversity index (also called the Shannon–Weiner index) parametrizes the diversity of a group containing multiple distinct subgroups. It is typically used in environmental science to determine the species biodiversity of a community. The biodiversity of an ecological community can be described by using the Shannon diversity … 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…
