Simpsons biodiversity index

Webb18 mars 2024 · Simpson’s diversity index (also called concentration index) was published by British statistician Edward Hugh Simpson (born 1922, living in Oxfordshire), who is mostly famous for his formulation of Simpson’s paradox. E.H.Simpson published the index in the 1949’s Nature’s paper entitled “Measurement of diversity”. WebbSo divided by one, one, two, three, one, two, three. Yep, six zeros is equal to that. And then you subtract that from one and you get, which is approximately equal to 0.142. And so we see very clearly when we use Simpson's diversity index that consistent with our intuition community two has a lower diversity index than community one.
