WebbDiversity measurement assumes that all individuals in a specific taxa are equivalent and that all types are equally different from each other (Peet 1974). A measure of diversity can be achieved by using indices built on the relative abundance of taxa. These indices (sometimes referred to as non-parametric indices) benefit from not making ... WebbSimpson's index of diversity. The 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).
