Definition

The Shannon-Weaver diversity index is based on communication theory. The uncertainty is measured by the Shannon Function “ H′.” This term is the measure corresponding to the entropy concept defined by
$$ H^{\prime}=-{\displaystyle \sum_{n=1}^n\left({pi}^{*} \ln\ {p}_{\mathrm{i}}\right)} $$
