The Bradley–Terry model is a probability model that can predict the outcome of a paired comparison. Given a pair of individuals i and j drawn from some population, it estimates the probability that the pairwise comparison i > j turns out true, as where pi is a positive real-valued score assigned to individual i. The comparison i > j can be read as "i is preferred to j", "i ranks higher than j", or "i beats j", depending on the application.

has abstract	The Bradley–Terry model is a probability model that can predict the outcome of a paired comparison. Given a pair of individuals i and j drawn from some population, it estimates the probability that the pairwise comparison i > j turns out true, as where pi is a positive real-valued score assigned to individual i. The comparison i > j can be read as "i is preferred to j", "i ranks higher than j", or "i beats j", depending on the application. For example, pi may represent the skill of a team in a sports tournament, estimated from the number of times i has won a match. then represents the probability that i will win a match against j. Another example used to explain the model's purpose is that of scoring products in a certain category by quality. While it's hard for a person to draft a direct ranking of (many) brands of wine, it may be feasible to compare a sample of pairs of wines and say, for each pair, which one is better. The Bradley–Terry model can then be used to derive a full ranking. (en) El modelo de Bradley–Terry es un modelo de probabilidad que puede predecir el resultado de una comparación pareada. Dado un par de individuos i y j extraídos de alguna población, se estima la probabilidad de que la comparación por pares i > j resulta cierta, como donde pi es una puntuación real positiva asignada al individuo i. La comparación i > j se puede leer como "i es preferible a j", "i ocupa un lugar más alto que j" o "i vence a j", según la aplicación. Por ejemplo, pi puede representar la habilidad de un equipo en un torneo deportivo, estimada a partir del número de veces que he ganado un partido. a continuación, representa la probabilidad de que i a ganar un partido contra j. Otro ejemplo utilizado para explicar el propósito del modelo es el de puntuar los productos de una determinada categoría por calidad. Si bien es difícil para una persona redactar una clasificación directa de (muchas) marcas de vino, puede ser factible comparar una muestra de pares de vinos y decir, para cada par, cuál es mejor. El modelo de Bradley–Terry se puede utilizar para obtener una clasificación completa. (es)
