Testing axial symmetry in multivariate location-scale linear regression
Šárka Hudecová, Miroslav Šiman
The article deals with the problem of testing conditional axial symmetry within a~multivariate linear heteroscedastic regression framework. A new test based on integrated rank scor…
Detection of mean changes in partially observed functional data
Šárka Hudecová, Claudia Kirch
We propose a test for a change in the mean for a sequence of functional observations that are only partially observed on subsets of the domain, with no information available on the…
Specification Tests for the Error--Law in Vector Multiplicative Errors Models
Šárka Hudecová, Simos G. Meintanis
We suggest specification tests for the error distribution in vector multiplicative error models (vMEM). The test statistic is formulated as a weighted integrated distance between t…
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, ZdenÄk 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…
