Abstract

fetched live from OpenAlex

Despite the funding agencies growing demands towards power analyses, we believe researchers are still not fully aware of the statistical power concept, of the possible benefits of power analysis in the planning phase and of the ways to increase the chances of significantly detecting a given effect in their study. The following review falls within this area of interest. We discuss the history of the concept of statistical power, the reasons for its ongoing neglect, its potential benefits to researchers, as well as actual ways to improve statistical power. We also touch upon the subject of the impact of power analysis on the scientific literature.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
