  Hutchins, Yuan, M., and Santangelo (2015) proposed the Relative Citation
Ratio (RCR) as a new field-normalized impact indicator. This study investigates
the RCR by correlating it on the level of single publications with established
field-normalized indicators and assessments of the publications by peers. We
find that the RCR correlates highly with established field-normalized
indicators, but the correlation between RCR and peer assessments is only low to
medium.
