The Incremental Validity of Psychological Testing and Assessment: Conceptual, Methodological, and Statistical Issues.
Bibliographic record
Abstract
There has been insufficient effort in most areas of applied psychology to evaluate incremental validity. To further this kind of validity research, the authors examined applicable research designs, including those to assess the incremental validity of test instruments, of test-informed clinical inferences, and of newly developed measures. The authors also considered key statistical and measurement issues that can influence incremental validity findings, including the entry order of predictor variables, how to interpret the size of a validity increment, and possible artifactual effects in the criteria selected for incremental validity research. The authors concluded by suggesting steps for building a cumulative research base concerning incremental validity and by describing challenges associated with applying nomothetic research findings to individual clinical cases.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
