Abstract

fetched live from OpenAlex

Like any statistical modeling procedure, results from both exploratory and confirmatory factor analysis are vulnerable to disproportionate influence from unusual or outlying cases.Because the common factor model is a type of multiple regression model, concepts from regression case diagnostics can be applied to factor analysis.For instance, Pek and MacCallum (2011) and Flora, LaBrish, and Chalmers (2012) present several useful techniques for detecting influential cases and demonstrate their utility in applied settings.However, extant factor analysis software packages generally do not implement these important case diagnostic methods; therefore, specialized software is required.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
