More precisely, at each time-step, the conditional distribution of the number of extracted balls of a certain color given the past is assumed to be hypergeometric. We prove some central limit theorems in the sense of stable convergence and of almost sure conditional convergence, which are stronger than convergence in distribution. The proven results provide asymptotic confidence intervals for the limit proportion, whose distribution is generally unknown. Moreover, we also consider the case of more urns subjected to some random common factors. publisher: arXiv date: 2015 type: Working Paper type: NonPeerReviewed format: application/pdf language: en rights: cc_by_nc identifier: http://eprints.imtlucca.it/3596/1/1504.06999v2.pdf identifier: Crimaldi, Irene Central limit theorems for a hypergeometric randomly reinforced urn.
