Symbol Calculation
citation count sum of citation counts for all works by the individual identified in Publish or Perish
e e is square root of the (sum of citations of all works contributing to h minus h2)
h h is the highest number for which h works have been cited at least h times (also based on works identified in Publish or Perish)
hm hm is the sum of works contributing to h fractionalized by the number of authors
Icumulative average of the four indicators above after standardizing each separately (M = 0, SD = 1)
