Abstract

fetched live from OpenAlex

In this paper, we discuss stochastic comparisons of the smallest and largest order statistics from independent heterogeneous exponential–Weibull random variables. Let X1,…,Xn be independent random variables with Xi∼EW(αi,βi,γi), i=1,…,n. Further, let X1∗,…,Xn∗ be another set of independent random variables with Xi∗∼EW(αi∗,βi∗,γi∗), i=1,…,n. First, when γ1=⋯=γn=γ1∗=⋯=γn∗ and a matrix with different parameters αi,βi changes to another matrix in the sense of multivariate chain majorization and row majorization, we investigate the usual stochastic order of the largest order statistics. Next, when α1=⋯=αn=α1∗=⋯=αn∗,β1=⋯=βn=β1∗=⋯=βn∗ and (γ1,…,γn)⪰m(γ1∗,…,γn∗), we establish the usual stochastic order of the largest and smallest order statistics. Finally, we provide sufficient conditions for the hazard rate order of the smallest order statistics.

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.
