Shannon's index equation

WebbShannon's index (H'), also known as the Shannon-Wiener index, is another measurement of species diversity given by the following formula: H'=- P Inp 1-1 In words, this formula means that we multiply each of the relative abundance values by the natural log of the relative abundance values, sum these products, and then take the negative of this sum.
