SCOPUS SNIP INDICATOR

Rejoinder to Moed (2010; at http://arxiv.org/abs/1005.4906): Our main objection is against developing new indicators which, like some of the older ones (for example, the “crown indicator” of CWTS), do not allow for indicating error because they do not provide a statistics, but are based, in our opinion, on a violation of the order of operations. The claim of validity for the SNIP indicator is hollow because the normalizations are based on field classifications which are not valid. Both problems can perhaps be solved by using fractional counting.http://www.scienceofsciencepolicy.net/publication/scopus-snip-indicator
