Measurement of Alpha Diversity Using Simpson Index

WebbAlpha diversity is a term used to describe the "within-sample" diversity. It's a measure of how diverse a single sample is, usually taking into account the number of different species observed. Alpha diversity metrics are also often weighted by the abundances at which the individual microbes are observed. There are a number of commonly-used ... WebbSimpson (1949) developed an index of diversity that is computed as: where ni is the number of individuals in species i, and N is the total number of species in the sample. An equivalent formula is: where pi is the proportional abundance for each species and R is the total number of species in the sample.
