This article develops semiparametric approaches for estimation of propensity scores and causal survival functions from prevalent survival data. The analytical problem arises when …
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 …

This paper proposes a new estimator for bivariate distribution functions under random truncation and random censoring. The new method is based on a polar coordinate …

We consider the problem of fitting a heteroscedastic median regression model from left- truncated and interval-censored data. It is demonstrated that the adapted Efron's self …

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 …
This study takes up the issue of left-side truncation (LST) in strategy research. Since reliable data on early-stage and failed firms are often unavailable for analysis, empirical findings are …
PS Shen - Journal of Applied Statistics, 2015 - Taylor & Francis
We study the problem of fitting a heteroscedastic median regression model with doubly truncated data. A self-consistency equation is proposed to obtain an estimator. We set up a …
