Abstract

fetched live from OpenAlex

Abstract This paper presents the generalized Lindley binomial (GLB) distribution, a novel probability distribution designed for the analysis of proportional data with excessive endpoints. The study delves into the probabilistic characteristics of the GLB distribution, including the probability mass function and the rth factorial moment function. Estimation of the distribution parameters in the GLB model, both with and without covariates, is addressed using the Fisher scoring algorithm and the EM algorithm. Furthermore, the paper explores techniques for model diagnosis and evaluates the goodness of fit for the proposed GLB model. To illustrate the performance of the derived EM algorithms in parameter estimation, a limited simulation study is conducted for both cases, with and without covariates, in the GLB model. The practical application of the proposed Lindley binomial regression model is demonstrated using the whitefly dataset.

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.
