Webb12 sep. 2024 · How is Simpson’s reciprocal index calculated? September 12, 2024 by Alexander Johnson. Using the values we found earlier, Simpson’s Index can be calculated as: D = 2,668 / (105* (105-1)) = 0.244. We can also calculate Simpson’s Index of Diversity as 1 – D = 1 – 0.244 = 0.756. We can also calculate Simpson’s Reciprocal Index as 1 / D ... 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).
