To overcome this obstacle, for probability measures supported on finitely many points, we derive the asymptotic distribution of empirical Wasserstein distances as the optimal value of a linear programme with random objective function. This facilitates statistical inference (e.g. confidence intervals for sample-based Wasserstein distances) in large generality. Our proof is based on directional Hadamard differentiability. Failure of the classical bootstrap and alternatives are discussed. The utility of the distributional results is illustrated on two data sets.<\/jats:p>","DOI":"10.1111\/rssb.12236","type":"journal-article","created":{"date-parts":[[2017,5,19]],"date-time":"2017-05-19T04:13:00Z","timestamp":1495167180000},"page":"219-238","source":"Crossref","is-referenced-by-count":103,"title":["Inference for Empirical Wasserstein Distances on Finite Spaces"],"prefix":"10.1093","volume":"80","author":[{"given":"Max","family":"Sommerfeld","sequence":"first","affiliation":[{"name":"University of G\u00f6ttingen \u00a0 Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Axel","family":"Munk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2017,5,18]]},"reference":[{"key":"2023022005320277000_","doi-asserted-by":"crossref","first-page":"904","DOI":"10.1137\/100805741","article-title":"Barycenters in the Wasserstein space","volume":"43","author":"Agueh","year":"2011","journal-title":"SIAM J.
