The Herfindahl-Hirschman Index (HHI) is a commonly accepted measure of market concentration. It is calculated by squaring the market share of each firm competing in a market and then summing the resulting numbers. It can range from close to zero to 10,000.

It is calculated by squaring the market share of each firm competing in a market and then summing the resulting numbers. It can range from close to zero to 10,000. The apnea-hypopnea index (AHI) is a scale that tells whether you have a sleep disorder called apnea and, if so, how serious it is. Sleep apnea is when you stop breathing for 10 seconds or more The Web of Science uses the H-Index to quantify research output by measuring author productivity and impact. H-Index = number of papers ( h ) with a citation number ≥ h . Example: a scientist with an H-Index of 37 has 37 papers cited at least 37 times. The h-index, or Hirsch index, measures the impact of a particular scientist rather than a journal. "It is defined as the highest number of publications of a scientist that received h or more citations each while the other publications have not more than h citations each."

A scientist has index h if h of her/his N papers have at least h citations each, and the search committee has to determine the appropriate "citation scale" for the 

The H-Index is a numerical indicator of how productive and influential a researcher is. It was invented by Jorge Hirsch in 2005, a physicist at the University of California. Originally, Professor The h-index was initially proposed by Hirsch1 to provide a global impact of a scientist’s contributions. The h-index, however, provides a rough approximation to a scientist’s multifaceted profile and thus fails to reflect a scientist’s cumulative scientific and research accomplishments.

The Herfindahl Index (H) ranges from 1/N to one, where N is the number of firms in the market. Equivalently, if percents are used as whole numbers, as in 75 instead of 0.75, the index can range up to 100 2 , or 10,000.

Methods: The Shannon diversity index (H) is another index that is commonly used to characterize species diversity in a community.Like Simpson's index, Shannon's index accounts for both abundance and evenness of the species present. The proportion of species i relative to the total number of species (p i) is calculated, and then multiplied by the natural logarithm of this proportion (lnp i).

The index consists of 10 common ADLs, 8 of which represent activities related to personal care while 2 are related to mobility. What are the key scores?
