A kernel test for quasi-independence
Tamara Fernández, Wenkai Xu, Marc Ditzhaus +1
We consider settings in which the data of interest correspond to pairs of ordered times, e.g, the birth times of the first and second child, the times at which a new user creates a…
Inferring median survival differences in general factorial designs via permutation tests
Marc Ditzhaus, Dennis Dobler, Markus Pauly
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 ha…
Permutation inference in factorial survival designs with the CASANOVA
Marc Ditzhaus, Arnold Janssen, Markus Pauly
We propose inference procedures for general nonparametric factorial survival designs with possibly right-censored data. Similar to additive Aalen models, null hypotheses are formul…
Permutation test for the multivariate coefficient of variation in factorial designs
Marc Ditzhaus, Łukas Smaga
New inference methods for the multivariate coefficient of variation and its reciprocal, the standardized mean, are presented. While there are various testing procedures for both pa…
Testing marginal homogeneity in Hilbert spaces with applications to stock market returns
Marc Ditzhaus, Daniel Gaigall
The paper considers a paired data framework and discuss the question of marginal homogeneity of bivariate high dimensional or functional data. The related testing problem can be en…
