A SIMPLE NONPARAMETRIC APPROACH OF SURVIVAL DATA WITH TWO-STAGE OUTCOMES OF DIFFERENT SCALES
Changyong Feng (USA), Carlo Ercoli (USA) and Hongyue Wang (USA)
|
Abstract: In this paper, we construct a simple nonparametric test to analyze the survival data consisting of observations from two sequential stages with different scales. Simulation studies show that this method has very good control of the type I error and turns out to be more powerful than the log-rank test. We apply our method to a study of dental research. |
Keywords and phrases: survival analysis, Wilcoxon rank-sum test, log-rank test. |
