Distributions for cited articles from individual subjects and years
作者：
Highlights：
• Three citation distributions were compared for citations from a single subject and year.
• Power law tail slope estimates are inaccurate for data for single subjects and years.
• Only hooked power law and discrete lognormal distributions should be considered for subject-and-year-based citation analysis.
• Lognormal parameters can be estimated more accurately than can hooked power law parameters.
