How do we measure inflation? Some measurement problems
Bibliographic record
Abstract
preparation of this paper. I would also like to thank the participants in the Ottawa Group meeting in Paris for helpful comments. Abstract: The paper describes methods used in the calculation of the Icelandic CPI and resembles a conditional COLI. Substitution is counted for by using the geometric mean and by allowing substitution between stores. Methods used for correction of shopping substitution bias (outlet substitution bias) are described. This bias increased when inflation rose suddenly in the year 2001 and was corrected by quality adjustment, mainly based on evaluation of different selection of goods. Store weights were adopted in April 2002 which makes such corrections easier. The main sources are cash receipts collected in the household budget survey. Additional sources include information gathered from the main retail groups.

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.
