DETERMINANTES DO TEMPO MÉDIO DE SUBSTITUIÇÕES NO FUTEBOL: UMA ANÁLISE DO CAMPEONATO BRASILEIRO DE 2014
Bibliographic record
Abstract
Este estudo analisa os padrões da primeira substituição de jogadores de cada time durante o intervalo ou o segundo tempo de jogos na primeira divisão do Campeonato Brasileiro de 2014. Foram usados modelos MQO (Mínimos Quadrados Ordinários) e Tobit, ambos com correção para heterocedasticidade. Os resultados mostram que times que estão ganhando tendem a fazer a primeira mudança nos momentos finais da partida. Consequentemente, substituições defensivas ocorrem antes das ofensivas. Também existem evidências de que a classificação no campeonato de ambas as equipes em campo tem influência no momento em que a alteração ocorre.

Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
