A multiple comparisons procedure for detecting differences between treatments and a control in two-factor experiments
Bibliographic record
Abstract
In many experiments researchers are interested in comparing several treat¬ment means with a control mean. Their primary interest is to determine whether any treatments are significantly better than the control Several test procedures have been proposed in the literature, but only few of them can pro¬vide simultaneous confidence lower bounds. A new test statistic is proposed to compare treatment means with a control mean in two-factor experiments. Some upper percentage points are tabulated. It yields sharp simultaneous confidence lower bounds for the differences of such means. The new test is forresponding author.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
