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 ... WebbDiversity index, one of "shannon" , "simpson" or "invsimpson". MARGIN. Margin for which …
