Webb31 juli 2024 · The Shannon diversity index is a commonly used measure of diversity. However, you cannot compare the two index values using classic hypothesis tests because you do not have replicated data. The Hutcheson t-test is a modified version of the classic t-test that provides a way to compare two samples. Webb23 okt. 2012 · We’ll begin with the commonly used Shannon index, which quantifies the uncertainty that any two species drawn from the community are different. Shannon diversity ranges from 0 (total certainty) to log (S) (total uncertainty). Let’s use function `diversity`, also in the `vegan` package, to calculate Shannon diversity for both …
