In the present paper the cost of sampling is assumed to be the cost of an incorrect choice for half of the sample programme (which is divided evenly between the two populations). The resulting loss function is considered when the choice is between two normal populations of known equal variance, the standard of performance being determined by the mean. Wald's (1950) minimax principle is used to determine fixed size and sequential sampling procedures, and the performance of these procedures is examined.<\/jats:p>","DOI":"10.1111\/j.2517-6161.1959.tb00331.x","type":"journal-article","created":{"date-parts":[[2018,12,7]],"date-time":"2018-12-07T06:45:31Z","timestamp":1544165131000},"page":"203-213","source":"Crossref","is-referenced-by-count":10,"title":["A Different Loss Function for the Choice between Two Populations"],"prefix":"10.1093","volume":"21","author":[{"given":"Rita","family":"Maurice","sequence":"first","affiliation":[{"name":"University College , London"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2018,12,5]]},"reference":[{"key":"2024090922035629300_cit1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1093\/biomet\/44.1-2.9","article-title":"Restricted sequential procedures","volume":"44","author":"Armitage","year":"1957","journal-title":"Biometrika."},{"key":"2024090922035629300_cit2","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1093\/biomet\/37.3-4.334","article-title":"Properties of some tests in sequential analysis","volume":"37","author":"Baker","year":"1950","journal-title":"Biometrika"},{"key":"2024090922035629300_cit3","first-page":"49","article-title":"Contribution to the discussion on the paper by Grundy, Healy & Rees","volume":"18","author":"Box","year":"1956","journal-title":"J.
