In this paper, we generalize their result from individual tetrad differences to sets of tetrad differences of a certain form, and we simplify their proof. The generalization allows tighter constraints to be placed on the set of models compatible with given data and thereby facilitates the search for parsimonious models for large data sets. <\/jats:p>","DOI":"10.1142\/s0218488596000123","type":"journal-article","created":{"date-parts":[[2004,10,26]],"date-time":"2004-10-26T12:05:18Z","timestamp":1098792318000},"page":"209-224","source":"Crossref","is-referenced-by-count":0,"title":["VANISHING TETRAD DIFFERENCES AND MODEL STRUCTURE"],"prefix":"10.1142","volume":"04","author":[{"given":"GLENN","family":"SHAFER","sequence":"first","affiliation":[{"name":"Department of Accounting and Information Systems, Faculty of Management &amp; RUTCOR, Rutgers University, Newark, NJ 07102, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ALEXANDER","family":"KOGAN","sequence":"additional","affiliation":[{"name":"Department of Accounting and Information Systems, Faculty of Management &amp; RUTCOR, Rutgers University, Newark, NJ 07102, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PETER","family":"SPIRTES","sequence":"additional","affiliation":[{"name":"Department of Philosophy, Carnegie Mellon University, Pittsburgh, PA 15213, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"container-title":["International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218488596000123","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T17:20:33Z","timestamp":1565198433000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218488596000123"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1996,6]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[1996,6]]}},"alternative-id":["10.1142\/S0218488596000123"],"URL":"https:\/\/doi.org\/10.1142\/s0218488596000123","relation":{},"ISSN":["0218-4885","1793-6411"],"issn-type":[{"value":"0218-4885","type":"print"},{"value":"1793-6411","type":"electronic"}],"subject":[],"published":{"date-parts":[[1996,6]]}}}
