In this talk I will revisit a novel approach known as Sequential Goodness-of-Fit (SGoF) test (Carvajal-Rodriguez et al, 2009) under the view of the new re-definition of significance which underlies the method. Advantages and disadvantages of SGoF&#8217;s sigificance criterion when compared to FDR will be discussed.<\/p>\n<p> <\/p>\n<h3>Bayesian selective inference<\/h3>\n<hr class=\"hr\" \/>\n<p>2011\/11\/04 &#8211; 12:50 h | Daniel Yekutieli, University of Tel Aviv.<\/p>\n<p> <\/p>\n<p><b>Abstract<\/b><\/p>\n<p>The term selective inference refers to marginal statistical inferences that are provided for parameters selected after viewing the data, where the selected parameters are typically the significant findings of a multiple testing procedure. I will discuss selective inference from a Bayesian perspective. I will show that if the parameter is elicited a non-informative prior, or if it is a fixed unknown constant, then it is necessary to adjust the Bayesian inference for selection. I will present a Bayesian framework for providing inference for selected parameters and Bayesian False Discovery Rate controlling methodology, that is a generalization of existing Bayesian FDR methods that are only defined in the two-group mixture model. I will illustrate the results by applying them to simulated data and data from a microarray experiment.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>November 4th 2011 Faculty of Economic and Business Sciences | Seminar 273 SGoF: a new approach to significance in multiple testing 2011\/11\/04 &#8211; 12:05 h &hellip; <a class=\"excerpt_more\" href=\"https:\/\/sidor.uvigo.es\/en\/sem-20111104\/\">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-4273","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\/4273\/"}],"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=4273"}],"version-history":[{"count":0,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/posts\/4273\/revisions\/"}],"wp:attachment":[{"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/media\/?parent=4273"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/categories\/?post=4273"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sidor.uvigo.es\/en\/wp-json\/wp\/v2\/tags\/?post=4273"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
