Negative Binomial Match Prediction: When Poisson Isn't Enough
Why some sports need an overdispersed scoring model — and how the Negative Binomial distribution captures blowouts that Poisson misses.
Poisson Match Prediction: Modeling Scorelines, Spreads, and Totals
How to use Poisson distributions to model match outcomes — generating scoreline probabilities, moneyline odds, spread prices, and totals.
