When I was a graduate student more than twenty five years ago, I was struggling to read
many statistical research papers. This is particularly true at the time when I had passed my …

The proportional hazards (PH) model is, arguably, the most popular model for the analysis of
lifetime data arising from epidemiological studies, among many others. In such applications …

This paper proposes a new estimation procedure for the survival time distribution with left-
truncated and right-censored data, where the distribution of the truncation time is known up …

Abstract Analysis of left-truncated and right-censored (LTRC) survival data has received
extensive interest. Many inference methods have been developed for the various survival …

We analyze left-truncated and right-censored (LTRC) data using Aalen's linear models. The
integrated square error (ISE) is used to select an optimal bandwidth of the weighted least …

Quantile regression methods have been used to estimate upper and lower quantile
reference curves as the function of several covariates. In this article, it is demonstrated that …

Cross-sectional sampling is often used when investigating inter-event times, resulting in left-
truncated and right-censored data. In this paper, we consider a semiparametric truncation …

The log-normal distribution is often used to model lifetime data due to its nonmonotonic
hazard rate. However, with left-truncated data the normal approximation fails due to the …

Left-truncation and right-censoring (LTRC) arise naturally in lifetime data. Data may be left-
truncated due to a limitation in the study design. Failure of a unit is observed only if it fails …

Survival analysis can be defined as a set of statistical methods for a data set that is dictated
by a well-defined time variable denoted as T until the occurrence of a well-defined event for …
