Query: Accounting for the Uncertainty in the Evaluation of Percentile Ranks   In a recent paper entitled "Inconsistencies of Recently Proposed Citation
Impact Indicators and how to Avoid Them," Schreiber (2012, at arXiv:1202.3861)
proposed (i) a method to assess tied ranks consistently and (ii) fractional
attribution to percentile ranks in the case of relatively small samples (e.g.,
for n < 100). Schreiber's solution to the problem of how to handle tied ranks
is convincing, in my opinion (cf. Pudovkin & Garfield, 2009). The fractional
attribution, however, is computationally intensive and cannot be done manually
for even moderately large batches of documents. Schreiber attributed scores
fractionally to the six percentile rank classes used in the Science and
Engineering Indicators of the U.S. National Science Board, and thus missed, in
my opinion, the point that fractional attribution at the level of hundred
percentiles-or equivalently quantiles as the continuous random variable-is only
a linear, and therefore much less complex problem. Given the quantile-values,
the non-linear attribution to the six classes or any other evaluation scheme is
then a question of aggregation. A new routine based on these principles
(including Schreiber's solution for tied ranks) is made available as software
for the assessment of documents retrieved from the Web of Science (at
http://www.leydesdorff.net/software/i3).
