For paired comparisons, we propose a measure to represent the degree of departure from the extended Bradley-Terry model. The measure is expressed by using the Kullback-Leibler information and it ranges between $0$ and $1$.
The measure is applied to the win-loss standings of professional baseball league in Japan.
