Semiparametric analysis of survival data with left truncation and right censoring

Let TT, CC and VV denote the lifetime, censoring and truncation variables, respectively. Assume that (C,V)(C,V) is independent of TT and P(C≥V)=1P(C≥V)=1. Let FF, QQ and GG denote the common distribution functions of TT, CC and VV, respectively. For left-truncated and right-censored (LTRC) data, one can observe nothing if T
