초록

본 논문에서는 하나의 이진공변량(binary covariate)을 갖는 가산위험모형(additive risk model)의 적합도를 검정하기 위한 검정법을 제안하였다. 제안된 검정법은 마팅게일잔차(martingale residual)에 기초한 Wei(1984)의 비례위험모형(proportional hazards model)의 적합도검정법을 가산위험모형으로 확장한 형태이다. 제안된 검정통계량의 점근성질을 유도하였고 실제자료에 적용하여 보았다.

This paper proposes a goodness-of-fit test for checking the adequacy of the additive risk model with a binary covariate. The test statistic is based on martingale residuals, which is the extended form of Wei(1984)'s test. The proposed test is shown to be consistent and asymptotically normally distributed under the regularity conditions. Furthermore, the test procedure is illustrated with two set of real data and the results are discussed.
