Abstract:	The Kaplan-Meier estimator can be used to estimate survival for left-truncated right-censored survival times, under the assumption of independence of the survival times and left truncation times. This paper presents semiparametric estimating equations for estimating survival when the left truncation time is correlated with survival. The approach uses a copula to describe the dependence structure between the survival time and the left truncation time. These estimating equations yield the Kaplan-Meier estimator if the independence copula is used.
