WebJun 26, 2024 · Footnote 5 The new diversity measure is not significantly correlated with Rao-Stirling diversity or the Simpson index, but—not surprisingly—with the Gini coefficient and with variety; these two factors are constitutive for the diversity in this approach in addition to the disparity. WebDiversity index, one of "shannon" , "simpson" or "invsimpson". MARGIN Margin for which the index is computed. base The logarithm base used in shannon. inverse Use inverse Simpson similarly as in diversity (x, "invsimpson"). groups A grouping factor: if given, finds the diversity of communities pooled by the groups. equalize.groups

WebThe Gini-Simpson quadratic index is a classic measure of diversity, widely used by ecologists. As shown recently, however, this index is not suitable for the measurement of beta diversity when the number of species is very large. The objective of this paper is to introduce the Rich- Gini-Simpson quadratic index which preserves all the qualities ...
