Abstract

fetched live from OpenAlex

When evaluating a new statistical test, it’s important to check the type 1 error (T1E) control, often achieved by the `theoretical' design S0. In whole-genome association analyses, people scan through large numbers of genes (Gs) for the ones associated with an outcome(Y). Y comes from an unknown alternative and is not associated with the majority of Gs, This reality can be represented by two `empirical’ designs, where S1.1 simulates Y from G then evaluates its association with independently generated Gnew; while S1.2 evaluates the association between permutated Yperm and G. Using scale tests, location tests with single and multiple Gs as examples, we show that not all designs are equal. For certain statistics, T1E inflation can only be revealed under 1empirical’ designs and doesn’t diminish as sample size increases. This important observation calls for new practices for methods evaluation and interpretation of T1E control.

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.
