초록

야구에서 타자의 능력을 측정하는 많은 세이버메트릭스 통계량들 중에서 대체선수대비승수(wins above replacement; WAR)은 가장 많이 쓰이는 통계량이다. WAR은 선수의 공격능력과 주루능력, 수비능력 등을 하나의 수치로 표현하는 방법이란 점에서 큰 장점을 가지고 있다. 본 논문에서는 지난 3년간(2013-2015년) 한국프로야구 기록 자료를 바탕으로 세이버메트릭스 변수들의 값을 구한 뒤, 이를 이용하여 WAR을 대체할 수 있는 타자능력지수를 제안하였다. 타자능력지수는 산술평균방법, 가중평균방법, 주성분회귀분석 등을 통해 산출하고 WAR과 비교하여 가장 관계가 높은 방법을 선택하였다.

Wins above replacement (WAR) is one of the most widely used statistic among sabermatrics statistics that measure the ability of a batter in baseball. WAR has a great advantage that is to represent the attack power of the player and the base running ability, defensive ability as a single value. In this study, we proposed a hitter ability index using the sabermetrics statistics that can replace WAR based on Korea Baseball Record Data of the last three years (2013-2015). First, we calculated Batter ability index through the arithmetic mean method, the weighted average method, principal component regression and selected the method that had high correlation with WAR.
