Abstract

fetched live from OpenAlex

A nonparametric method for computing tolerance limits in small to moderate non-normal samples is proposed. The method is based on confidence intervals for quantiles. The quantiles are first estimated using a kernel quantile estimator which is known to have an asymptotic normal distribution. Approximate confidence intervals can be easily constructed using this normal approximation. The proposed kernel quantile limits are compared by simulation with the classical normal tolerance limits as well as some tolerance limits that are known to have excellent behaviour in large samples. The simulation results indicate that the kernel quantile limits can be somewhat conservative, but they are often much more accurate than the other two methods.

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.
