Abstract

fetched live from OpenAlex

BACKGROUND: I use Benford's law to assess whether there is misreporting of coronavirus disease of 2019 (COVID-19) deaths in the USA. METHODS: I use three statistics to determine whether the reported deaths for US states are consistent with Benford's law, where the probability of smaller digits is greater than the probability of larger digits. RESULTS: My findings indicate that there is under-reporting of COVID-19 deaths in the USA, although the evidence for and the extent of under-reporting does depend on the statistic one uses to assess conformity with Benford's law. CONCLUSIONS: Benford's law is a useful diagnostic tool for verifying data and can be used before a more detailed audit or resource intensive investigation.

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.
