Abstract

fetched live from OpenAlex

Canadian Sport Policy calls for an increase in the number and diversity of Canadians participating in sport between 2012-2022 (Canadian Sport Policy, 2012). Understanding the determinants of physical activity and sport participation is central to achieving this objective. We estimate double hurdle models to analyze the individual determinants of physical activity in Canada. Separate consideration of participation and time spent decisions is important for untangling the effects of income, age, gender, and family structure on choices. Income is positively associated with participation in swimming, golfing, weight lifting, and running. Time spent walking, exercising at home, golfing, weight lifting, and running decreases with income. Wage rates are generally positively associated with participation and time spent.

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.
