The method uses conjugate models whereby the marginal likelihood for the data between consecutive changepoints is tractable. Inclusion of hyperpriors gives a near automatic algorithm providing a robust alternative to popular filtering recursions approaches in cases which may be sensitive to prior information. Three real examples are used to demonstrate the proposed approach.", "revisions": [ { "version": "v1", "updated": "2010-11-12T14:58:32.000Z" } ], "analyses": { "keywords": [ "simulation-based bayesian analysis", "markov chain monte carlo method", "generate approximate posterior samples", "popular filtering recursions approaches", "retrospective multiple changepoint problems" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1011.2932W" } } }
