DOI: 10.1002/sim.9399
Abstract: The restricted mean survival time (RMST) is a clinically meaningful summary measure in studies with survival outcomes. Statistical methods have been developed for regression analysis of RMST to investigate impacts of covariates on RMST, which… read more here.

DOI: 10.1002/sim.9429
Abstract: To compare two or more survival distributions with interval‐censored data, various nonparametric tests have been proposed. Some are based on the Gρ$$ {G}^{\rho } $$ ‐family introduced by Harrington and Fleming (1991) that allows flexibility… read more here.

DOI: 10.1007/s00184-019-00712-x
Abstract: Various nonparametric test statistics have been proposed for censored data. Two-sample nonparametric testing plays an important role in biometry. While most of two-sample nonparametric tests intend to detect a shift in location or in scale,… read more here.

DOI: 10.1080/00949655.2019.1628963
Abstract: ABSTRACT Length-biased data, which are often encountered in engineering, economics and epidemiology studies, are generally subject to right censoring caused by the research ending or the follow-up loss. The structure of length-biased data is distinct… read more here.
