Shannon index and simpson index
WebbDetermining population diversity is an important part of the statistics of an ecosystem. The Shannon diversity index is one of several statistical indices used to measure species richness. There are several other diversity indices such as Simpson’s index and the Shannon Weiner index, however. Shannon’s index will be our main focus. What is the … WebbRoutledge (1979) suggested that the Simpson Con-centration and Shannon index were the only members of the Hill family that were worthy of consideration, with the latter retained due to its links to information theory and entropy. The study by Lande (1996) has shown that Simpson diversity is preferable to both the Simpson concentration and ...
