WebbDescription Calculates Pielou's measure of species evenness, i.e. J = H'/ln (S) where H' is Shannon Weiner diversity and S is the total number of species in a sample, across all samples in dataset. Usage evenness (x) Arguments x A vector or matrix of species abundances (e.g. counts). WebbShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i p i log b p i, where p i is the proportional abundance of species i and b is the base of the logarithm. …

Shannon’s Diversity Index Basic Concepts For categorical data, there is no mean or median and so we can’t use the measures of variation described in Measures of Variability. Instead, we use a measure of the distribution of observations among the categories. Visa mer For categorical data, there is no mean or median and so we can’t use the measures of variation described in Measures of Variability. Instead, we … Visa mer As observed above,H′ is largest occurs when all the categories have the same number of observations (homogeneity of categories), in which case all the pi are equal. In this case, J′ = … Visa mer The following is an improved version of Shannon’s index which takes into account that some population categories may not be present in the random sample.
