👉 Bradley Math, also known as the Bradley-Terry model, is a statistical framework used to analyze pairwise comparisons in situations where entities (like individuals, animals, or items) are ranked based on their relative preferences or abilities. It models the probability that one entity prefers another, given their relative standings. The core idea is that entities with similar preferences are more likely to be compared favorably to each other, while those with different preferences are less likely. The model uses a logistic function to estimate the probability of preference, where the inverse of the relative standing (e.g., position A over B) is multiplied by a parameter that captures the strength of preference. This approach is widely applied in fields such as ecology (species competition), marketing (customer preference), and social sciences (individual ranking). By estimating these probabilities, Bradley Math helps predict outcomes in competitive scenarios and understand the dynamics of preference formation.
