This urn generalizes a model studied in Berti et al. (2004), May et al. (2005), and in Crimaldi (2007), and it has natural applications in clinical trials. Indeed, the model includes both delayed and missing (or null) responses. Moreover, a connection with the conditional identity in distribution of Berti et al. (2004) is given. publisher: Taylor & Francis date: 2008 type: Article type: PeerReviewed identifier: Crimaldi, Irene and Leisen, Fabrizio Asymptotic results for a generalized Pólya urn with “multi-updating” and applications to clinical trials.
