Abstract

Parallelism tests are proposed for slope in the simple linear regression models. In this paper, we suggest the parametric test using HSD testing method (Tukey,1953) and distribution-free test using Kruskal-wallis (1952) for more than three slopes. Monte Carlo simulation study is adapted to compare the power of the proposed methods with Wilks' Lambda multivariate procedure.

단순선형 회귀모형의 기울기에 대한 평행성 검정법을 제안하였다. 세 군 이상에서 기울기에 대하여 Tukey (1953)가 제안한 HSD방법을 이용한 모수적 검정법과 Kruskal-Wallis (1952) 검정법을 이용한 비모수적 검정법을 각각 제안하였다. 또한 모의실험을 통하여 기존의 검정법과 제안한 검정법의 검정력을 비교하였다.
