Diversity index, Fisher
WebFisher's alpha - a diversity index, defined implicitly by the formula S=a*ln(1+n/a) where S is number of taxa, n is number of individuals and a is the Fisher's alpha. Berger-Parker dominance: simply the number of individuals in the most dominant taxon relative to n. WebFigure 15: TechniFilter Plus, Inverse Fisher Transform of RSI. After computing the report (or exploration) of the database, you can use a pre-saved filter or build a custom filter using a selection of the Report Columns (formulas). This example locates all stocks that the inverse Fisher transform has either crossed from below to above -0.5 or 0.5. css cursor on drag

Diversity measurement assumes that all individuals in a specific taxa are equivalent and that all types are equally different from each other (Peet 1974). A measure of diversity can be achieved by using indices built on the relative abundance of taxa. These indices (sometimes referred to as non-parametric indices ... css cursor 手
