Following up from Monday's post on SNIP2 and SJR2. I finally got a copy of the full database. 16866 journals have both a non-zero SNIP and a non-zero SJR for 2011. It's hard to understand how a journal could have a positive SJR but a zero SNIP, but there are a lot of such journals. There are a total of 32060 journals in the database. I plotted the two indicators for the subsample of journals against each other:
The relationship is pretty linear in log-log space except that SJR is truncated at 0.1. The correlation between the two series is 0.75 (0.77 for the log series).
