Abstract

Nonparametric procedures in a randomized block design was proposed by Friedman (1937) as a general alternative as well as suggested as a test for ordered alternatives by Page (1963). These methods are used for the rank of treatments in each block. In this paper, we proposed nonparametric procedures using aligned method proposed by Hodges and Lehmann (1962) to reduce among block information and based on placement suggested by Kim (1999) in a randomized block design. We also perform a Monte Carlo study to compare the empirical powers of the proposed procedures and established method.

랜덤화 블록 계획법을 검정하는 비모수 방법은 일반 대립가설에서 Friedman (1937), 순서형 대립가설에서 Page (1963)가 제안한 방법이 있다. 이 방법은 각 블록 내 처리 간 순위를 이용해 처리 간의 차이를 검정하는 방법이다. 본 논문에서는 Hodges와 Lehmann (1962)이 제안한 정렬방법을 이용하여 블록 간 정보의 손실을 줄이고, Orban과 Wolfe (1982)가 제안한 위치를 확장하여, Kim (1999)이 제안한 대조군과 처리군의 방법을 이용하여 랜덤화 블록 모형에서 새로운 비모수 검정 방법을 제안하였다. 또한 Monte Carlo 모의실험을 통해 제안방법과 기존의 검정 방법을 비교하였다.
