Keming Yu is Department of Mathematical Sciences, Brunel University, UK We considera regression model in which the variable of interest is censored. We present various nonparametric estimators of the conditional distribution function and of conditional quantiles. In a simulation study, we compare the performance of these estimators. Moreover, the local linear estimator of conditional quantile is applied on a dataset dealing with the effect of age on survival time of kidney transplant patients.
Key Words: censored data conditional quantile kernel estimator local linear estimator survival analysis
