Abstract

fetched live from OpenAlex

Abstract Summary statistics and data visualizations are often used to explore data and draw preliminary conclusions. Although valuable, these tools do not always reveal the underlying patterns and trends in the data and can sometimes be misleading. We describe an approach for teaching the need for more advanced statistical analysis using multiple linear regression. Our approach is based on using a method we developed for generating alternative multivariate data sets where all the variables (both independent and dependent) have the same summary statistics. However, we can deliberately change the statistical significance of one (or more) of the independent variables in the regression to illustrate why it is important to go beyond simple descriptive measures and examine inferential statistics on the inherent relationships in the data. Implementation of this methodology is provided in the R statistical programming language and an add‐in for Excel spreadsheets.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction

Teacher imitation

Not 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.
