Shannon's index

WebbThe Shannon index is a mathematical tool for calculating the proportional abundance of species in a given location. This type of species abundance provides an indication of the biological diversity in that area. It is related to information entropy in that the formula Of the two concepts is identical. WebbL' indice di Shannon-Wiener H' è un indice di diversità usato in statistica nel caso di popolazioni con un numero infinito di elementi. dove p j è la proporzione della j-esima specie (Σ j p j = 1) e s è il numero delle specie. Dividendo H' con il valore massimo possibile H' max =log e (s), si ottiene un indice compreso tra 0 e logaritmo di k.
