The class of tests covered by this admissibility result contains the Anderson and Rubin (1949, <jats:italic>Annals of Mathematical Statistics<\/jats:italic> 20, 46\u201363) test. Thus, there is no conventional statistical sense in which the Anderson and Rubin (1949) test \u201cwastes degrees of freedom.\u201d In addition, it is shown that the test proposed by Moreira (2003, <jats:italic>Econometrica<\/jats:italic> 71, 1027\u20131048) belongs to the closure of (i.e., can be interpreted as a limiting case of) the class of tests covered by our admissibility result.<\/jats:p>","DOI":"10.1017\/s0266466608090312","type":"journal-article","created":{"date-parts":[[2009,5,26]],"date-time":"2009-05-26T09:32:22Z","timestamp":1243330342000},"page":"806-818","source":"Crossref","is-referenced-by-count":20,"title":["ADMISSIBLE INVARIANT SIMILAR TESTS FOR INSTRUMENTAL VARIABLES REGRESSION"],"prefix":"10.1017","volume":"25","author":[{"given":"Victor","family":"Chernozhukov","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Hansen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Jansson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,6,1]]},"reference":[{"key":"S0266466608090312_ref17","doi-asserted-by":"publisher","DOI":"10.1198\/073500102288618658"},{"key":"S0266466608090312_ref16","doi-asserted-by":"publisher","DOI":"10.2307\/2171753"},{"key":"S0266466608090312_ref15","doi-asserted-by":"publisher","DOI":"10.1002\/9780470316559"},{"key":"S0266466608090312_ref14","doi-asserted-by":"publisher","DOI":"10.1111\/1468-0262.00438"},{"key":"S0266466608090312_ref11","doi-asserted-by":"publisher","DOI":"10.1111\/1468-0262.00353"},{"key":"S0266466608090312_ref10","doi-asserted-by":"publisher","DOI":"10.1257\/000282803321946912"},{"key":"S0266466608090312_ref7","doi-asserted-by":"publisher","DOI":"10.2307\/2171740"},{"key":"S0266466608090312_ref6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-0262.2007.00764.x"},{"key":"S0266466608090312_ref5","first-page":"122","volume-title":"Advances in Economics and Econometrics: Theory and Applications, Ninth World Congress","volume":"III","author":"Andrews","year":"2007"},{"key":"S0266466608090312_ref3","doi-asserted-by":"crossref","unstructured":"Andrews D.W.K. , Moreira M.J. , & Stock J.H.
