The **Bradley–Terry model** is a probability model for the outcome of pairwise comparisons between items, teams, or objects. Given a pair of items 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 might represent the skill of a team in a sports tournament and
