Implication

This study predicts Olympic medal outcomes for 2028 using a combined model, suggesting non-linear factors are key.

Key Points

  • The random forest-arima model predicts the United States will lead with 92 medals, followed by China and Japan.
  • Data cleaning through non-negative least squares reveals trends, with the United States expected to achieve 37 gold medals.
  • Countries like Australia and Italy are projected to experience significant medal fluctuations in future Olympics.
  • The model indicates that several countries, including SAM, may achieve their first Olympic medals based on probability estimates.
