Are the discretised lognormal and hooked power law distributions plausible for citation data?
作者:
Highlights:
• Neither the discretised lognormal nor the hooked power law are plausible for citation counts from a single Scopus category and year.
• Parameter variations in fitted citation distributions may be due to mixed sub-fields within single subject areas.
• Large sample sizes and simplifying assumptions are needed to test whether a distribution is mixed.
