Webb7 juni 2024 · There is no such groups argument in diversity because it is not well defined: Do you mean the average diversity of the sampling units in a group, or the diversity of the average of sampling units in a group? They are different things and it is best to explicitly do what you want this index to do. The first thing is easier: just calculate diversities for SUs … WebbCommon alpha diversity statistics include: Shannon: How difficult it is to predict the identity of a randomly chosen individual. Simpson: The probability that two randomly chosen individuals are the same species. Inverse Simpson: This is a …
WebbWhen diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types, or … WebbThe Simpson's index is defined as D = sum p_i^2. This is equivalent to -1 * 1 / exp (R2), with R2 the renyi index for alpha=2. With this index, 0 represents infinite diversity and 1, no diversity. As this is counterintuitive behavior for a diversity index, we use 1 - D (Gini, 1912; Simpson, 1949).
