Abstract

fetched live from OpenAlex

Inference in generalized linear mixed models (GLMM) remains a topic of debate.\nBaayen, Davidson, and Bates (2008) outlines criticism against conventional ways of\nperforming inference for GLMMs. There are various alternatives proposed but lit-\ntle consistency is found on which is the most reasonable. Our focus is on assessing\ntemporal trends for mainly ecological count data. That is, we hope to provide a prag-\nmatic approach to Poisson GLMMs for ecological researchers within the statistical\nprogramming environment R. To achieve this, we start by providing a description of\nthe selected estimation and inferential procedures. We then complete a large scale\nsimulation to evaluate each of the estimation methods. We implement a power analy-\nsis to assess each of the selected inferential procedures. We then go on to apply these\nprocedures to data sampled by The National Parks of Canada. Finally, we conclude by giving a summary of our ?ndings and outlying work for the future.

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.
