Global rank tests for multiple, possibly censored, outcomes. [PDF]
Biometrics, 2016 Clinical trials often collect multiple outcomes on each patient, as the treatment may be expected to affect the patient on many dimensions. For example, a treatment for a neurological disease such as ALS is intended to impact several dimensions of ...

An Aligned Rank Transform Procedure for Multifactor Contrast Tests [PDF]
ACM Symposium on User Interface Software and Technology, 2021 Data from multifactor HCI experiments often violates the assumptions of parametric tests (i.e., nonconforming data). The Aligned Rank Transform (ART) has become a popular nonparametric analysis in HCI that can find main and interaction effects in ...

On universally consistent and fully distribution-free rank tests of vector independence [PDF]
Annals of Statistics, 2020 Rank correlations have found many innovative applications in the last decade. In particular, suitable rank correlations have been used for consistent tests of independence between pairs of random variables.

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.

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.

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 ...
