An H below 0.01 (or 100) indicates a highly competitive industry. An H below 0.15 (or 1,500) indicates an unconcentrated industry. The h-index, originally described in 2005 by it’s namesake Jorge Hirsch, is a measurement that aims to describe the scientific productivity and impact of a researcher. The h index is a metric for evaluating the cumulative impact of an author’s scholarly output and performance; measures quantity with quality by comparing publications to citations. The h index corrects for the disproportionate weight of highly cited publications or publications that have not yet been cited. The h-index is used along with applicants research & skills to measure their impact What Is a Good H-Index Required for an Academic Position?

Since the h-index is modeled as a non-negative integer, we will take the integer part of that solution, which we shall denote with h w, (12) h W = W q − 1 N ⋅ log q − 1 log q − 1 where z denotes the integer part of z. The h-index was rapidly taken up as a tool for assessing researchers, perhaps in part due to its simplicity; a scientist has an h-index of n, if she has n papers, with n or more citations. Take for example Dr. Wheatus, Dr. Wheatus has published six papers, with 256, 8, 8, 7, 5, and 2 citations. The Herfindahl Index (H) ranges from 1/N to one, where N is the number of firms in the market.

It is explained by the formula: s H = -∑ (P i * ln P i) i=1. where, H = the Shannon diversity index The Hirsch or h-index continues to be one of the most popular author-based metrics, despite some of its flaws and limitations. In some cases, citations to some academics’ work are increasing at a phenomenal pace, and in some exceptional cases such as Highly Cited Researchers (HCRs), whether alive or deceased, citation counts to their work have reached tens or hundreds of thousands, with h In the Theory and practice of the g-index, Leo Egghe (2006) aims to improve on the h-index by giving more weight to highly-cited articles.
