Abstract

Some rank score tests are proposed for testing the equality of all sampling distribution functions against umbrella location-scale alternatives in k-sample problem. Only the case of known peak $\ell$ is considered. Under the null hypothesis and a contiguous sequence of unbrella location-scale alternatives, the asymptotic properties of the proposed test statistics are investigated. Also, the asymptotic local powers are compared with each others. The results show that the tests based on the Chen-Wolfe rank analogue statistic are more powerful than others for unequally spaced umbrella location-scale alternatives and robust.

본 논문에서는 $\kappa$-표본 문제에서 우산형 위치-척도 대립가설에 대한 순위검정법들을 연구하였다. 위치모수와 척도모수의 변동에 민감한 순위점수에 기초한 검정통계량들을 제안하였다. 우산형 대립가설의 정점이 알려진 경우를 다루었으며 귀무가설과 대립가설하에서의 점근성질도 아울러 조사되었다. 모수들간의 간격이 같지않는 우산형 위치-척도모형에서 Chen-Wolfe의 동위회귀 추정량을 이용한 순위통계량에 의존한 검정법이 효율적이었으며 또한 아주 안정적이었다.
