However inferences about a linear combination of K independent proportions L=\\Sigma ?ipi have had very little attention paid to them (focused exclusively on the classic Wald method), despite their great practical importance. This investigation approaches the problem from the more efficient viewpoint of the score method, gives in addition a general proof of Agresti&#8217;s heuristic method (consisting of adding a certain number of successes and failures to the original results before applying Wald&#8217;s method).<\/p>\n<p>Numerical analysis indicates that the score method is the optimal method in comparison with other methods, with the additional theoretical advantage that it also verifies the desirable properties of &#8220;spatial convexity&#8221; and &#8220;parametric convexity&#8221;.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>October 15th 2013 Faculty of Economic and Business Sciences | Sal\u00f3n de Grados Classic Wald Method and Score Method about a linear combination of proportions &hellip; <a class=\"excerpt_more\" href=\"https:\/\/sidor.uvigo.es\/en\/sem-20131015\/\">Continued<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[101],"tags":[],"class_list":["post-4259","post","type-post","status-publish","format-standard","hentry","category-seminars"],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/posts\/4259\/"}],"collection":[{"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/posts\/"}],"about":[{"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/types\/post\/"}],"author":[{"embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/users\/2\/"}],"replies":[{"embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/comments\/?post=4259"}],"version-history":[{"count":0,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/posts\/4259\/revisions\/"}],"wp:attachment":[{"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/media\/?parent=4259"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/categories\/?post=4259"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/tags\/?post=4259"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
