Calculating Shannon

WebbShannon 's entropy index is a measure of the entropy, that applies to any numerical data, developed by Claude Shannon in the 1940s. It measures the frequencies of appearance of the items, and the more they are different, the more difficult it will be to predict the content (thus a greater uncertainty, more randomness, and thus a greater entropy).

WebbIt has also been called the Shannon index and the Shannon-Weaver index. Similar to the Simpson index, the first step is to calculate P i for each category (e.g., species). You then multiply this number by the log of the number. While you may use any base, the natural log is commonly used (ln). The index is computed from the negative sum of ... WebbWhen diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types, or haplotypes. The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage.

Vegan calculates Shannon index like: H ′ = − ∑ i = 1 R p i ln p i. And Gini-Simpson like: 1 − λ = 1 − ∑ i = 1 R p i 2. So the Hill numbers should be: H 1 = e x p ( H ′)
