Abstract

In various sports such as baseball, football and volleyball, league systems are organized with the same teams, and the teams compete against each other every season. In this article, we consider the modeling of winning percentage using state space model. We apply the models above to the data of the Central League in Nippon Professional Baseball (NPB) for the period 1950-2004.
