The Confidence Bands for the Survival Function in Random Censorship Model

임의중도절단된 자료에서 생존함수의 동시신뢰대 구성

We consider the problem of obtaining the confidence bands for the survival function with incomplete data. It is a rather simple procedure for constructing confidence bands of survival function. This method uses the weak convergence of normalized cumulative hazard estimator to a mean zero Gaussian process whose distribution can be easily approximated through simulation. Finally, we compare the performance of the proposed confidence bands through Monte Carlo simulation and we applied to construct the proposed bands with the Leukemia patient data.

임의중도절단된 생존시간자료에서 생존함수에 대한 동시신뢰대를 근사식이나 표없이 구성하는 간단한 방법을 제안하였다. 그리고 모의실험을 통하여 기존의 동시신뢰대와 포함확률측면에서 서로 비교하고, 실제자료에 적용하여 보았다.
