Abstract

fetched live from OpenAlex

Statistical significance tests done with low statistical power levels can result in reports of exaggerated effect sizes. Funnel graphs can show these exaggerations for a given area of research by revealing a negative correlation between a study’s sample size on the y -axis and the effect size obtain by the study on the x -axis. A recent paper by Fritz, Scherndl, and Kühberger (2013) recommended that effect sizes should not be reported when there is a negative correlation between sample size and effect size for a given research area. This recommendation fails to consider magnitudes of the negative correlations and thereby misses the opportunity to mitigate effect size exaggerations and approximate more correct effect size estimates. This comment explains both the incorrectness of the recommendation and the approach and calculations necessary to correct effect size estimates.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
