McCall's area transformation versus the integrated impact indicator (13)

摘要

In a study entitled "Skewed Citation Distributions and Bias Factors: Solutions to two core problems with the journal impact factor," Mutzand Daniel (2012) propose (i) McCall's (1922) Area Transformation of the skewed citation distribution so that this data can be considered as normally distributed (Krus & Kennedy, 1977), and (ii) to control for different document types as a co-variate (Rubin, 1977). This approach provides an alternative to Leydesdorff and Bornmann's (2011) Integrated Impact Indicator (13). As the authors note, the two approaches are akin.
