Trajectories of SCI Journal Impact Factors: Code and Derived Data

This record contains the analysis code and derived data for the manuscript “Trajectories of SCI Journal Impact Factors: A Time-Series Clustering Analysis of 10,129 Journals”. It includes Python scripts for data preprocessing, balanced-panel construction, clustering, robustness analysis, and figure generation, as well as derived datasets generated specifically for this study, including clustering assignments, summary tables, and figure/table source files. The original journal metric data were obtained from Clarivate’s Journal Citation Reports (JCR), which is a third-party data source subject to licensing restrictions. The full original JCR dataset is therefore not redistributed in this record. This record is intended to support reproducibility of the published analysis to the extent legally permitted.
