Shannon weaver index formula

WebbAccording to Shannon (1948; see also Shannon and Weaver 1949), a general communication system consists of five parts: − A source S, which generates the message to be received at the destination. − A transmitter T, which turns the message generated at the source into a signal to be transmitted. 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…
