Title: | Bootstrapping quantiles in a fixed design regression model with censored data | Authors: | VAN KEILEGOM, Ingrid VERAVERBEKE, Noel |
Issue Date: | 1998 | Source: | J. Statist. Planning Inf., 69(1). p. 115-131 | Abstract: | We consider the problem of estimating the quantiles of a distribution function in a fixed design regression model in which the observations are subject to random right censoring. The quantile estimator is defined via a conditional Kaplan-Meier type estimator for the distribution at a given design point. We establish an a.s. asymptotic representation for this quantile estimator, from which we obtain its asymptotic normality. Because a complicated estimation procedure is necessary for estimating the asymptotic bias and variance, we use a resampling procedure, which provides us, via an asymptotic representation for the bootstrapped estimator, with an alternative for the normal approximation | Document URI: | http://hdl.handle.net/1942/180 | DOI: | 10.1016/S0378-3758(97)00126-2 | ISI #: | 000074353700009 | Type: | Journal Contribution | Validations: | ecoom 1999 |
