This can be extended under various assumptions, covering nonnegative as well as invertible matrices, to a law of large numbers for the norm of a vector on which the matrices act. We prove corresponding precise large deviation results, generalizing the Bahadur-Rao theorem to this situation. Therefore, we obtain a third-order Edgeworth expansion for the cumulative distribution function of the vector norm. This result in turn relies on an application of the Nagaev-Guivarch method. Our result is then used to study matrix recursions, arising e.g. in financial time series, and to provide precise large deviation estimates there.", "revisions": [ { "version": "v1", "updated": "2014-05-26T08:51:24.000Z", "comment": "32 pages", "journal": null, "doi": null }, { "version": "v2", "updated": "2015-02-09T08:54:45.000Z" } ], "analyses": { "subjects": [ "60F10", "60H25" ], "keywords": [ "random matrices", "precise large deviation estimates", "large numbers", "corresponding precise large deviation results", "study matrix recursions" ], "note": { "typesetting": "TeX", "pages": 39, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1405.6505B" } } }
