In 3-4 sentences, explain win probability models. State any key formula.

# Win Probability Models Win probability models estimate the likelihood that a team will win a game based on the current game state (score, time remaining, possession, field position, etc.). These models are typically built using historical data and logistic regression or machine learning techniques to predict outcomes from similar past situations. **Key formula (logistic regression form):** $$P(\text{Win}) = \frac{1}{1 + e^{-(\beta_0 + \beta_1 x_1 + \beta_2 x_2 + ... + \beta_n x_n)}}$$ where the *x* variables represent game state features (point differential, time remaining, etc.) and the β coefficients are estimated from historical data. The model outputs a probability between 0 and 1, which updates throughout the game as conditions change.
