We investigate the \nconsistency and the speed of convergence of these estimated \nefficiency scores (or of the radial distances) in the very \ngeneral setup of a multi-output and multi-input case. It \nis shown that the speed of convergence relies on the smoothness \nof the unknown frontier and on the number of inputs and \noutputs. Furthermore, one has to distinguish between the \noutput- and the input-oriented cases.<\/jats:p>","DOI":"10.1017\/s0266466698146042","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:45:46Z","timestamp":1027763146000},"page":"783-793","source":"Crossref","is-referenced-by-count":294,"title":["A NOTE ON THE CONVERGENCE OF NONPARAMETRIC DEA ESTIMATORS \nFOR PRODUCTION EFFICIENCY SCORES"],"prefix":"10.1017","volume":"14","author":[{"given":"Alois","family":"Kneip","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byeong U.","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u00e9opold","family":"Simar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[1998,12,1]]},"container-title":["Econometric Theory"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0266466698146042","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,10]],"date-time":"2019-05-10T15:40:36Z","timestamp":1557502836000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0266466698146042\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,12]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1998,12]]}},"alternative-id":["S0266466698146042"],"URL":"https:\/\/doi.org\/10.1017\/s0266466698146042","relation":{},"ISSN":["0266-4666","1469-4360"],"issn-type":[{"value":"0266-4666","type":"print"},{"value":"1469-4360","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,12]]}}}
