Abstract

fetched live from OpenAlex

The purpose of this paper is to investigate the asymptotic properties of Bernstein estimators for the distribution and density function under ψ-weak dependence. This work focuses on a type of weak dependence that is different from the notion of mixing. The asymptotic properties, namely, strong consistency and asymptotic normality are established under some regularity conditions. A simulation study based on a ψ-weak dependent model that is not necessarily mixing shows that the Bernstein estimator can outperform the Rosenblatt kernel density estimator.

Not 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.
