Given the set of \ntransformed moment conditions, we then show that the conditions \nfor partial redundancy of an additional set of moment conditions \ngiven an original set of moment conditions simply become the \nconditions for full redundancy of the second subset of transformed \nmoment conditions given the first subset of transformed moment \nconditions. Thus the transformed moment conditions proposed \nin this paper unify partial redundancy of moment conditions \nwith full redundancy of moment conditions. Using transformed \nmoment conditions, we then straightforwardly derive necessary \nand sufficient conditions for partial redundancy of one or two \nsubset(s) of moment conditions given the other when the large \nset of moment conditions consists of three subsets of moment \nconditions. The paper also provides several easily checkable \nsufficient conditions for partial redundancy of one set of moment \nconditions given other sets of moment conditions.<\/jats:p>","DOI":"10.1017\/s0266466602182132","type":"journal-article","created":{"date-parts":[[2002,11,14]],"date-time":"2002-11-14T22:01:57Z","timestamp":1037311317000},"page":"531-539","source":"Crossref","is-referenced-by-count":1,"title":["PARTIAL REDUNDANCY OF MOMENT CONDITIONS"],"prefix":"10.1017","volume":"18","author":[{"given":"Hailong","family":"Qian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2002,5,16]]},"container-title":["Econometric Theory"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0266466602182132","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,7]],"date-time":"2019-04-07T20:32:58Z","timestamp":1554669178000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0266466602182132\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,4]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2002,4]]}},"alternative-id":["S0266466602182132"],"URL":"https:\/\/doi.org\/10.1017\/s0266466602182132","relation":{},"ISSN":["0266-4666","1469-4360"],"issn-type":[{"value":"0266-4666","type":"print"},{"value":"1469-4360","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,4]]}}}
