![THE H FACTOR
A scientist has index h if h of [his/her] Np papers
have at least h citations each,
and the other (Np - h) papers have at most h citations
each.
THE SNIP
Since 2010 SNIP = Source Normalized Impact per Paper
SNIP (Journal)= RIP/CP
RIP = Raw Impact per Paper
CP = Citation Potential
(average number of references in the articles that cite a given journal)
Ò Only cited references from articles in the census period, and which refer to
articles within the target period are counted
Ò Only cited references indexed in the Scopus database are counted
