In the end we all die. More interesting than the death event itself is the time component: at what age does one die and what characteristics make some individuals die earlier than …

One of the principal goals of the quasar investigations is to study luminosity evolution. A convenient one-parameter model for luminosity says that the expected log luminosity, T …
There is often delayed entry into observational studies, which results in left truncation. In the estimation of the distribution of time‐to‐event from left‐truncated data, standard survival …

The hazard ratios resulting from a Cox's regression hazards model are hard to interpret and to be converted into prolonged survival time. As the main goal is often to study survival …

The partial likelihood (PL) function has been mainly used for the Cox proportional hazards models with censored data. The PL approach can also be used for analyzing left-truncated …

Survival data are very common in medical science, actuarial science, astronomy, demography, and many other scientific areas. The most typical characteristic of survival data …

Abstract The Kaplan-Meier and closely related Lynden-Bell estimators are used to provide nonparametric estimation of the distribution of a left-truncated random variable. These …
This paper reconsiders several results of historical and current importance to nonparametric estimation of the survival distribution for failure in the presence of right-censored observation …

In transplant studies, the patients must survive long enough to receive a transplant, which induces left-truncation. The assumption of independence between failure and truncation …
