Abstract

fetched live from OpenAlex

This study develops R estimators of the fixed effects in an experiment done over correlated baseline series.Besides a simple parametric approach we investigate linear mixed models procedures also.The random errors are independent within OLUWAGBOHUNMI AWOSOGA et al. 132 series but are dependent between several baseline series.The JR method seems more appropriate in term of its empirical type I error and the power of the test for the case of independence within but dependence between series than other methods (i.e., CT, WW, and LME) considered in this study.We illustrated the robustness of the procedures on a real data set which contained some outliers.Our robust procedures were much less sensitive to the effect of the outliers than the traditional analysis based on LS.A simulation study over situations similar to that of the data set confirmed the validity of our new approaches.The study also showed the robustness of efficiency of our approach over that of the traditional analysis.

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.
