Abstract

Typical Nonparametric methods for randomized block design with replications are two methods proposed by Mack (1981) and Mack and Skillings (1980). This method is likely to cause information loss because it uses the average of repeated observations instead of each repeated observation in the processing of each block. In order to compensate for this, we proposed a test method using linear placement statistics, which is a score function applied to the joint placement method proposed by Chung and Kim (2007). Monte Carlo simulation study is adapted to compare the power with previous methods.

반복이 있는 랜덤화 블록 계획법(randomized block design with replications)에서의 대표적인 검정법은 Mack이 제안한 방법과 Mack과 Skillings이 제안한 방법이 있다. 이 방법은 각 블록의 처리에서 반복된 각 관측값 대신에 반복된 관측값들의 평균을 이용하여 순위를 매기기 때문에 정보의 손실이 발생할 가능성이 있다. 이를 보완하기 위해 본 논문에서는 Chung과 Kim (2007)이 제안한 결합위치(joint placement) 방법에 점수함수(score function)를 적용한 선형위치통계량(linear placement statistics)을 이용한 검정방법을 제안하였다. 또한 Monte Carlo simulation study를 통해 기존의 방법들과 검정력을 비교하였다.
