Elsevier's Scopus has a revised SNIP indicator for journal ranking

The modified SNIP indicator of Elsevier, as recently explained by Waltman et

unfortunate in the case of scientometric distributions because these can be
extremely skewed (Seglen, 1992 and 1997). The new indicator cannot (or
hardly) be reproduced independently when used for evaluation purposes, and
