Warsserstein Tests for Equality of Several Groups for Distributional Data
Warsserstein Tests for Equality of Several Groups for Distributional Data
<title>Abstract</title> The study aims to develop a Wasserstein test for the equality of groups for distri-butional data using Wasserstein geometry to account for the geometric distance between empirical distributions. Non-Euclidean data, such as distributional data, do not exist in a linear vector space; therefore, subtraction or addition may not have …
