Notes on the Bayesian approach

  • This uses a conjugate Normal–Inverse-Gamma model for each horse’s latent speed and draws posterior predictive samples; win probability is the chance a simulated next speed is the maximum in its field.
  • Heavy tails come from the Student-t predictive, improving robustness with sparse/noisy histories.
  • Recency weighting (half-life in race counts) down-weights old races; set BAYES_HALF_LIFE_RACES <- NA to turn off.
  • If you later want true MCMC/hierarchical effects, we can wire a brms/rstanarm alternative and keep the same max-of-field simulation to produce Win% (Bayes, naive).
