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.
