RMST‐based multiple contrast tests in general factorial designs
Several methods in survival analysis are based on the proportional hazards assumption.
However, this assumption is very restrictive and often not justifiable in practice. Therefore …

Computation of the Mann–Whitney effect under parametric survival copula models
K Nakazono, YC Lin, GY Liao, R Uozumi, T Emura - Mathematics, 2024 - mdpi.com
The Mann–Whitney effect is a measure for comparing survival distributions between two
groups. The Mann–Whitney effect is interpreted as the probability that a randomly selected …

Estimation of the Mann–Whitney effect in the two-sample problem under dependent censoring
T Emura, JH Hsu - Computational Statistics & Data Analysis, 2020 - Elsevier
Abstract The Mann–Whitney effect is a nonparametric measure for comparing the
distribution between two groups, which can be estimated by right-censored data. However …

CASANOVA: Permutation inference in factorial survival designs
We propose inference procedures for general factorial designs with time‐to‐event
endpoints. Similar to additive Aalen models, null hypotheses are formulated in terms of …

Factorial survival analysis for treatment effects under dependent censoring
Factorial analyses offer a powerful nonparametric means to detect main or interaction effects
among multiple treatments. For survival outcomes, for example, from clinical trials, such …

A survival tree based on stabilized score tests for high-dimensional covariates
T Emura, WC Hsu, WC Chou - Journal of Applied Statistics, 2023 - Taylor & Francis
ABSTRACT A survival tree can classify subjects into different survival prognostic groups.
However, when data contains high-dimensional covariates, the two popular classification …

Inferring median survival differences in general factorial designs via permutation tests
Factorial survival designs with right-censored observations are commonly inferred by Cox
regression and explained by means of hazard ratios. However, in case of non-proportional …

Studentized permutation method for comparing two restricted mean survival times with small sample from randomized trials
Recent observations, especially in cancer immunotherapy clinical trials with time‐to‐event
outcomes, show that the commonly used proportional hazard assumption is often not …
