Abstract
A class of U-statistics matrices is introduced to obtain the distribution of the matrices of the Spearman and Kendall correlation coefficients between the components of a random vector.These results are used to construct nonparametric tests of independence between two sets of variables based on three measures of multivariate relationship.The tests are illustrated by an example and a simulation study is performed to compare the tests based on Kendall's matrix with those based on Spearman's matrix.(i \ n+l\ { /, n + 1 ij = l,...,m,

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
