computes hill number from a distribution The Hill numbers quantify biodiversity. The importance of the abundance distribution increases with increasing Hill order. For q=0, the Hill number is the richness, for q=1, it is the exponential Shannon entropy and for q=2, it is the inverse Simpson index. Note that the Hill order can also be a fraction, e.g. 0.5.
