One-sample location tests based on center-outward signs and ranks
Daniel Hlubinka, Šárka Hudecová
A multivariate one-sample location test based on the center-outward ranks and signs is considered, and two different testing procedures are proposed for centrally symmetric distrib…

Functional Sample Problem via Multivariate Optimal Measure Transport-Based Permutation Test
Šárka Hudecová, Daniel Hlubinka, Zdeněk Hlávka
The null hypothesis of equality of distributions of functional data coming from samples is considered. The proposed test statistic is multivariate and its components are based…

Multivariate quantile-based permutation tests with application to functional data
Zdeněk Hlávka, Daniel Hlubinka, Šárka Hudecová
Permutation tests enable testing statistical hypotheses in situations when the distribution of the test statistic is complicated or not available. In some situations, the test stat…
