WebbIn other words, it tends to 0 when your data set is very unbalanced. log. . k when all your classes are balanced of the same size n k. Therefore, you could use the following measure of Balance for a data set: Balance = H log k = − ∑ i = 1 k c i n log c i n. log k. which is equal to: 0 for an unbalanced data set. WebbShannon or Shannon–Weaver (or Shannon–Wiener) index is defined as H' = -\sum_i p_i \log_ {b} p_i H ′ =−∑i pi logb pi, where p_i pi is the proportional abundance of species i i and b b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 b =2 (which makes sense, but no real difference).
