Published in 2025 at "Statistics in Medicine"

DOI: 10.1002/sim.70012

Abstract: In oncology studies, the assumption of proportional hazards is often questionable due to factors such as the presence of cured patients, a delayed treatment benefit, and possible treatment switching. The restricted mean survival time (RMST)… read more here.

Published in 2021 at "Statistics in medicine"

DOI: 10.1002/sim.9110

Abstract: Dealing with high-dimensional censored data is very challenging because of the complexities in data structure. This article focuses on developing a variable selection procedure for censored high-dimensional data with the AFT models using the Modified… read more here.

Published in 2022 at "Statistics in Medicine"

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.

Published in 2022 at "Statistics in Medicine"

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.

Published in 2021 at "Structural and Multidisciplinary Optimization"

DOI: 10.1007/s00158-020-02828-5

Abstract: In this paper, joint probability distribution for the size and mass of deep-sea manganese nodules is investigated and reliability-based design optimization (RBDO) of a deep-sea pilot mining robot is performed. As the size and mass… read more here.

Published in 2019 at "Metrika"

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.

Published in 2017 at "Journal of Mechanical Science and Technology"

DOI: 10.1007/s12206-017-0209-y

Abstract: The effect of censored data on the average life of products was analyzed, and the relationships between the censored data and the reliability evaluation results were also given. A series of regression analysis function relationship… read more here.

Published in 2020 at "Journal of The Korean Statistical Society"

DOI: 10.1007/s42952-020-00051-y

Abstract: The additive hazards model is one of the most popular regression models for analyzing failure time data, especially when one is interested in the excess risk or risk difference. Although a couple of methods have… read more here.

Published in 2019 at "Geoderma"

DOI: 10.1016/j.geoderma.2019.03.016

Abstract: Soil thickness (ST) is a crucial factor in earth surface modelling and soil storage capacity calculations (e.g., available water capacity and carbon stocks). However, the observed depths recorded in soil information systems for some profiles… read more here.
