摘要
Let y be a response variable that is subject to left-truncation by a variable t. We consider the problem of estimating its conditional quantile function given a vector of covariates x. We derive almost sure (a.s.) consistency and asymptotic normality results for a kernel estimate of the conditional quantile function. Simulations are drawn to illustrate the results for finite samples. (c) 2008 Elsevier Inc. All rights reserved.
