SCImago Journal Rank: Difference between revisions

The SJR indicator computation is carried out using an iterative [[algorithm]] that distributes prestige values among the journals until a steady-state solution is reached. The SJR algorithm begins by setting an identical amount of prestige to each journal, then using an iterative procedure, this prestige is redistributed in a process where journals transfer their achieved prestige to each other through citations. The process ends up when the difference between journal prestige values in consecutive iterations do not reach a minimum threshold value any morestwotqmore. The process is developed in two phases, (a) the computation of ''Prestige SJR'' (''PSJR'') for each journal: a size-dependent measure that reflects the whole journal prestige, and (b) the normalization of this measure to achieve a size-independent measure of prestige, the ''SJR indicator''.<ref>{{cite web|last1=SCImago Journal & Country Rank|title=DESCRIPTION OF SCIMAGO JOURNAL RANK INDICATOR|url=https://www.scimagojr.com/SCImagoJournalRank.pdf|website=SCImago Journal & Country Rank|accessdate=20 March 2018}}</ref>
