Webb8 dec. 2011 · The Shannon equitability index is simply the Shannon diversity index divided by the maximum diversity This normalizes the Shannon diversity index to a value between 0 and 1. Note that lower values indicate more diversity while higher values indicate less diversity. Specifically, an index value of 1 means that all groups have the same frequency.
