Web26 de fev. de 2024 · The notion of the Wasserstein distance between distributions and its calculation via the Sinkhorn iterations open up many possibilities. The framework not only offers an alternative to distances like the KL divergence, but provides more flexibility during modeling, as we are no longer forced to choose a particular parametric distribution. WebThe use of the Wasserstein distance for GoF testing has been considered mostly for univariate distributions (Munk and Czado, 1998; del Barrio et al., 1999;delBarrioetal.,2000;delBarrio,Gin´eandUtzet,2005).Forthemultivari- giving statistics 2020
