Censored Median Regression Using Weighted Empirical Survival and Hazard Functions
基于加权经验生存函数与风险函数的删失中位数回归
For median regression models that regress the median of the survival time or a transform thereof on the covariates, some semi-parametric estimators that include the intercept component are introduced when the survival time may be censored. These new median regression estimators do not require estimating the censoring distributions. They can be viewed as an extension of the sample median to the censored regression model. These estimators are based on some weighted empirical…
