Shannon entropy richness evenness

WebbShannon's index of diversity H' is derived from information theory, originally in the context of information in telephone systems ( Shannon, 1948 ). It combines both evenness and richness in a single measure. H' has no intuitive interpretation in terms of probability and is sensitive to sample size. WebbAs a result you will get the Shannon entropy, Shannon equitability, true diversity (number equivalent of Shannon entropy), Berger-Parker index, Simpson dominance, Gini-Simpson index and Simpson equitability.
