Core Concepts
A data-driven model that selects a subset of remaining games to conclude a suspended sports league season, while producing an end-of-season ranking similar to that of the full season.
Abstract
The content discusses a methodology for concluding suspended sports leagues, such as the NBA, in a shortened time frame. The key highlights are:
Professional sports leagues may be suspended due to events like the COVID-19 pandemic, leading to the need to conclude the season in a shortened time frame.
The authors propose a two-phase approach that combines predictive and prescriptive analytics:
In the predictive phase, they use historical data to train binary classification models that predict the outcomes of the remaining games.
In the prescriptive phase, they formulate stochastic optimization models that select a subset of the remaining games to play, with the objective of minimizing the dissimilarity between the rankings produced by the shortened season and the full season.
The authors introduce novel ranking-based objectives within their stochastic optimization models, and develop efficient solution techniques, including a tailored Frank-Wolfe algorithm.
Numerical experiments on past NBA seasons show that the authors' models can produce shortened seasons with 25-50% fewer games while still generating end-of-season rankings that are highly similar to the full season rankings.
The authors also provide a model extension that ensures each team's strength-of-schedule is not materially impacted by the choice of shortened season.
