Abstract
In this paper, we study the ordering properties of the second sample spacing arising from multiple-outlier exponential models in terms of the likelihood ratio order. Let X1,…,Xn [Y1,…,Yn] be independent exponential random variables with X1,…,Xp [Y1,…,Yp] having common hazard rate λ1 [λ1∗] and Xp+1,…,Xn [Yp+1,…,Yn] having common hazard rate λ2 [λ2∗]. Let D2:n and D2:n∗ denote the corresponding second sample spacing, respectively. It is proved here that D2:n is stochastically greater than D2:n∗ in the sense of the likelihood ratio order, under two different kinds of parameter conditions. The results established here strengthen and generalize some of the results known in the literature. Two applications are also presented to illustrate the results.

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
