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… WebbEl índice de Shannon, de Shannon-Weaver o de Shannon-Wiener se usa en ecología u otras ciencias similares para medir la biodiversidad específica.
