Median Regression for Left and Right Censored Data

Abstract��

In many applications
involving follow-up studies, individuals' lifetimes may be subject
to both left and right censoring. In this paper we consider
regressing the median of the lifetime variable or a transformation
thereof on the corresponding covariates when the lifetimes are
subject to both left and right censoring and the values of both
censoring variables are always observable. A semiparametric
inferential procedure is proposed and the asymptotic properties of
the proposed method are discussed. We also propose an alternative
empirical likelihood based inferential procedure for the regression
coefficients vector. Moreover, we make some discussion on classical
doubly censored data whose censoring variables cannot always be
observed. The proposed methods are illustrated by some simulation
studies.

Keywords�� Left and right censoring   empirical likelihood   least absolute deviations   median regression.
