reanalyze

Reanalyze is a verb meaning to analyze again or to reassess information, data, or conclusions that were previously examined. It often involves incorporating new evidence, alternative assumptions, or advanced methods. The form reanalyze is common in American English; the British variant is reanalyse.

Applications of reanalysis appear across disciplines. In science and research, it is used to revisit results with updated data, statistical techniques, or model assumptions. In data science, datasets may be reanalyzed to uncover new patterns or validate findings. In meteorology and climatology, past weather records are reanalyzed to produce revised reanalysis datasets. In the humanities and journalism, reanalysis can involve reexamining documents, translations, or reported conclusions after new information emerges.

Considerations accompany reanalysis efforts. Transparency and documentation are essential; reanalysis should specify data sources, methods, and rationales. Results may revise conclusions, influencing policy or practice. It can improve reliability but also risks bias if driven by preference for a preferred outcome or selective data. Peer review and preregistration of methods can help mitigate these concerns.
