| Abstract(in English) | In sumo wrestling, which is a Japanese traditional sport, lots of sumo wrestlers suffer from injuries through actual bouts. Because sumo wrestling loses its fun by increasing the number of injury occurrences of sumo wrestlers, the necessity of creating systems to reduce injury occurrences of sumo wrestlers has been discussed for a long time (e.g., kosho system). However, most of the discussions have not been done based on the quantitative evaluation of the injury. Therefore, we propose a stochastic model of injury occurrences for sumo wrestlers and evaluate the risk of injury occurrences of sumo wrestlers. In particular, we estimate the probability of an injury occurrence for a sumo wrestler in a grand sumo tournament. While previous research modeled the injury occurrence by using the non-homogeneous Poisson process that is well-known in reliability engineering, we model it by the Hawkes process. We reveal that the proposed model is fitter for the actual data than the previous model. |
