内容記述
There are some Hitters' evaluation indexes as batting average, number of homeruns, hit points, and so on. However, the hit rate, the number of homeruns, etc. are only an aspect of batters and it is difficult to objectively evaluate focusing on multiple evaluation indexes. The OERA model was proposed to evaluate batters fairly and accurately. However, OERA model does not include sacrifice hits and flies. It may not be suitable for Japan's small baseball. In this paper, we propose an improved OERA model incorporating with sacrifice hist and flies which are not adopted in the original OERA model. Experimental results showed that the improved OERA model can be a model that consider both the batting average rate and hit points.
