Statistical Football prediction is a method used in sports betting, to predict the outcome of football matches by means of statistical tools. The goal of statistical match prediction is to outperform the predictions of bookmakers [ citation needed ] [ dubious – discuss ] , who use them to set odds on the outcome of football matches.
The expected goals metric is generally calculated by determining the likelihood of a shot being scored based on various factors, taken from the moment before the player shoots. These factors may vary depending on the statistical model, but include the distance to the goal, angle, quality of the shot, and other characteristics.
Football Power Index (abbreviated as FPI) is a predictive rating system developed by ESPN that measures team strength and uses it to forecast game and season results in American football. Each team's FPI rating is composed of predictive offensive, defensive, and special teams value, as measured by a function of expected points added (EPA).
That is, a prediction of 80% that correctly proved true would receive a score of ln(0.8) = −0.22. This same prediction also assigns 20% likelihood to the opposite case, and so if the prediction proves false, it would receive a score based on the 20%: ln(0.2) = −1.6. The goal of a forecaster is to maximize the score and for the score to be ...
Advanced Football Analytics (originally Advanced NFL Stats) has its EPA (expected points added) and WPA (win probability added) for NFL players. Grantland lead football writer Bill Barnwell created the first metrics focused on predicting the future performance of an individual player, the Speed Score , which he referenced in a piece written for ...
The template contains three sets of parameters: scoring, wins-losses and discipline.As such, one type of parameter cannot be used when another type is active (e.g. a scoring parameter cannot be used when the type "discipline" is active).
Initially the correlation between the formula and actual winning percentage was simply an experimental observation. In 2003, Hein Hundal provided an inexact derivation of the formula and showed that the Pythagorean exponent was approximately 2/(σ √ π) where σ was the standard deviation of runs scored by all teams divided by the average number of runs scored.

Probabilistic forecasting summarizes what is known about, or opinions about, future events. In contrast to single-valued forecasts (such as forecasting that the maximum temperature at a given site on a given day will be 23 degrees Celsius, or that the result in a given football match will be a no-score draw), probabilistic forecasts assign a probability to each of a number of different ...
