Here we apply some recent results for conditional moments of diversity measures under Gibbs-type priors to derive a Bayesian nonparametric estimator of Gini-Simpson's index under the Hubbell Unified Neutral Theory of Biodiversity and Biogeography. Potential applications are also illustrated.Cerquetti, ...
The Gini index is also related to the Pietra index — both of which measure statistical heterogeneity and are derived from the Lorenz curve and the diagonal line.[92][93][28] In certain fields such as ecology, inverse Simpson's index 1 / �{\displaystyle 1/\lambda } is used to quan...
