Reference curve sampling variability in one-sample log-rank tests. [PDF]
PLoS ONE, 2022 The one-sample log-rank test is the method of choice for single-arm Phase II trials with time-to-event endpoint. It allows to compare the survival of patients to a reference survival curve that typically represents the expected survival under standard of

Estimation of treatment effects in weighted log-rank tests [PDF]
Contemporary Clinical Trials Communications, 2017 Non-proportional hazards have been observed in clinical trials. The log-rank test loses power and the standard Cox model generally produces biased estimates under such conditions.

Saddlepoint approximations for linear rank tests with left-truncated, right-censored, and cross-sectional data under randomized block design [PDF]
Scientific ReportsLeft-truncated data arise when events are only recorded if they occur after a pre-specified time point, while right censoring occurs when the exact event time is not fully observed.

Log-rank and stratified log-rank tests
Statistical Theory and Related Fields, 2023 In randomized clinical trials with right-censored time-to-event outcomes, the popular log-rank test without adjusting for baseline covariates is asymptotically valid for treatment effect under simple randomization of treatments but is too conservative ...

Change-Point Rank Tests with Epidemic Alternative [PDF]
The Egyptian Statistical Journal, 2006 A simple linear rank test statistics for a possible epidemic-type distributional change are introduced and studied. The proposed rank statistics are extensions of the Damico's two-sample test statistic [ Damico, J.

Circulation, 2006 Nonparametric statistical methods are useful tools for data analysis when there is reason to believe that the outcome variables of interest may fail certain distributional assumptions required for parametric methods. Variables may be ordered categories in nature and thereby not suitable for analysis methods that assume normally distributed variables ...

La somme des rangs de Wilcoxon, ses moments, sa distribution nulle,avec illustration et compléments [PDF]
Tutorials in Quantitative Methods for Psychology, 2020 This paper delves into Wilcoxon's sum-of-ranks $R$ statistic (and Mann-Whitney's translated equivalent $U$) for testing the difference between two groups.

Testing for the rank of a covariance operator
The Annals of Statistics, 2022 How can we discern whether the covariance operator of a stochastic process is of reduced rank, and if so, what its precise rank is? And how can we do so at a given level of confidence? This question is central to a great deal of methods for functional data, which require low-dimensional representations whether by functional PCA or other methods.

On the Ranking of Test Match Batsmen [PDF]
Journal of the Royal Statistical Society Series C: Applied Statistics, 2018 SummaryRanking sportsmen whose careers took place in different eras is often a contentious issue and the topic of much debate. We focus on cricket and examine what conclusions may be drawn about the ranking of test batsmen by using data on batting scores from the first test in 1877 onwards. The overlapping nature of playing careers is exploited to form
