Simpson Index: Definition and Formula, Interpretation and Example

The Simpson index was introduced in 1949 by Edward H. Simpson to measure the degree of concentration when individuals are classified into types. The same index was rediscovered by Orris C. Herfindahl in 1950. The square root of the index had already been introduced in 1945 by the economist Albert O. Hirschman. As a result, the same measure is usually known as the Simpson index in ecology, and as the Herfindahl index or the Herfindahl–Hirschman index (HHI) i… cynthia lollis

Calculating Simpson

Webbthese same data showed that if Shannon's diversity val-ues were plotted against 10g2 of species richness, the plot was linear (Fig. 2). Simpson's index expresses the probability of inter-specific encounter and its values are on a non-linear probability scale. Using a table provided by Fisher and Yates (1963), Simpson's diversity values were trans- WebbSimpson's index is a similarity index (the higher the value the lower in diversity). If you want to use it as a diversity index you can subtract it to 1 (i.e. 1-S). WebbHe Simpson's index it is a formula that is used to measure the diversity of a community. It is commonly used to measure biodiversity, that is, the diversity of living beings in a given place. However, this index is also useful to measure the diversity of elements such as schools, places, among others. In ecology, the Simpson index is often used ... cynthialon781 gmail.com
