Conditions for $\\sup_B|C_n(B)|$ to converge stably (in particular, in distribution) are given, where $B$ ranges over a suitable class of measurable sets. These conditions apply when $(X_n)$ is exchangeable or, more generally, conditionally identically distributed (in the sense of Berti et al. [Ann. Probab. 32 (2004) 2029--2052]). By such conditions, in some relevant situations, one obtains that $\\sup_B|C_n(B)|\\stackrel{P}{\\to}0$ or even that $\\sqrt{n}\\sup_B|C_n(B)|$ converges a.s. Results of this type are useful in Bayesian statistics.", "revisions": [ { "version": "v1", "updated": "2010-01-13T13:14:33.000Z" } ], "analyses": { "keywords": [ "dependent data", "predictive distributions", "convergence", "conditions", "paper deals" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
