Abstract

fetched live from OpenAlex

The purpose of this paper is to use Monte Carlo simulations to evaluate the performance of six most popular statistics for testing the goodness of fit of a parametric density function. The first three tests in this study are based on the empirical distribution function which are simple and widely used. The other three are based on directed and non-directional divergence measures and derived from minimum relative entropy (MinxEnt) principle, m-spacing method and kernel method. This study aims to evaluate the behavior of these tests by examining the rejection rates under the hypothesis. It is shown that the tests based on the directed divergence measure give a good approximation to the given significance levels and are more powerful than other tests against the given alternative distributions. It also suggests that the statistics based on the MinxEnt estimator detect the distribution with higher kurtosis better than others.

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.
