The high average effciency is the result of assuming that the units in the effcient\nset are 100% effcient. If this assumption is not valid, this results in an overestimation of the\nefficiencies, which will be larger for a smaller number of units. Samples of various sizes are used\nto find the related bias in the effciency estimation. The samples are drawn from a large scale\napplication of DEA to bank branch efficiency. The effects of different assumptions as to returns\nto scale and the number of inputs and outputs are investigated.<\/jats:p>","DOI":"10.1155\/s1173912698000030","type":"journal-article","created":{"date-parts":[[2007,3,8]],"date-time":"2007-03-08T07:44:28Z","timestamp":1173339868000},"page":"51-64","source":"Crossref","is-referenced-by-count":32,"title":["Sampling size and efficiency bias in data envelopment analysis"],"prefix":"10.1080","volume":"2","author":[{"given":"Mohammad R.","family":"Alirezaee","sequence":"first","affiliation":[{"name":"University of Calgary and Teacher Training University, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Murray","family":"Howland","sequence":"additional","affiliation":[{"name":"University of Calgary, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cornelis","family":"van de Panne","sequence":"additional","affiliation":[{"name":"University of Calgary, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"301","container-title":["Journal of Applied Mathematics and Decision Sciences"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/archive\/1998\/618768.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/1998\/618768.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T14:22:54Z","timestamp":1723126974000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/ads\/1998\/618768\/abs\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1998,1,1]]}},"alternative-id":["618768"],"URL":"https:\/\/doi.org\/10.1155\/s1173912698000030","relation":{},"ISSN":["1173-9126"],"issn-type":[{"type":"print","value":"1173-9126"}],"subject":[],"published":{"date-parts":[[1998,1,1]]}}}
