We utilize an extended generalized gamma distribution for the error term of the AFT model and a logistic regression for the cure proportion (i.e. the incidence part). We investigate some issues concerning this model, including estimation, variable selection, model simplification and prediction. We then apply this method to an Alzheimer disease database, which consists in 241 at-risk patients followed-up between 1998 and 2008 with regular checks for the appearance of mild cognitive impairment.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>July 8th 2014 Faculty of Economic and Business Sciences | Room 105 Prediction and variable selection in AFT cure models with interval censored data 2014\/07\/08 &hellip; <a class=\"excerpt_more\" href=\"https:\/\/sidor.uvigo.es\/en\/sem-20140708\/\">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-4251","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\/4251\/"}],"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=4251"}],"version-history":[{"count":0,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/posts\/4251\/revisions\/"}],"wp:attachment":[{"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/media\/?parent=4251"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/categories\/?post=4251"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/tags\/?post=4251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
