Abstract:

We consider a 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.
