WebbIn order to quantify the differences between the two fields, we will calculate a diversity index called the Simpson Index (D). This index shows the probability that two individuals randomly selected from a sample will belong to the same species. The equation for Simpson's Index (D) is Σ (n-1). Webb11 apr. 2024 · The commonly used metrics/indices are Shannon, Inverse Simpson, Simpson, Gini, Observed and Chao1. These indices do not take into account the phylogeny of the taxa identified in sequencing. Phylogenetic diversity (Faith’s PD) uses phylogenetic distance to calculate the diversity of a given sample.
