Abstract

It is common in practice to use mean squared error(MSE) for prediction. Recently, Park and Shin (2005) and Jones et al. (2007) studied prediction based on mean squared relative error(MSRE). We proposed a new nonparametric way of prediction based on MSRE substituting Jones et al. (2007) and provided a small simulation study which highly supports the proposed method.

공변량 값이 주어졌을 때 반응변수의 값을 예측하는 데에는 평균제곱오차를 최소로 하는 것을 고려하는 것이 보통이지만, 최근 Park과 Shin (2005), Jones 등 (2007) 등에서 평균제곱오차대신 평균제곱상대오차에 기반한 예측을 연구한바 있다. 이 논문에서는 Jones 등 (2007)의 방법을 대체할 새로운 비모수적 예측법을 제안하고, 제안된 방법의 유효성을 뒷받침하는 간단한 모의실험 결과를 제공한다.
