Abstract

Let (X,Y) be the variable of interest, where Y is the possibly right-censored lifetime and X is a p-dimensional covariate. We introduce a generalized ACL (Abdushukurov, Cheng, Lin) estimator F~XY of FXY(x,y)=P(X[less-than-or-equals, slant]x,Y[less-than-or-equals, slant]y) and we prove [integral operator][phi] dF~XY-->[integral operator][phi] dFXY a.s. for any integrable function [phi] under an extended Koziol-Green model of proportional censorship.
