We show that one can achieve an $O(N^{-2/3})$ rate with particular choices of the centering and scaling constants. The arguments here also shed light on more complicated cases of Laguerre and Jacobi ensembles, in both unitary and orthogonal versions. Numerical work shows that the suggested constants yield reasonable approximations, even for surprisingly small values of N.", "revisions": [ { "version": "v2", "updated": "2012-10-19T08:12:49.000Z" } ], "analyses": { "keywords": [ "tracy-widom law", "fast approach", "largest eigenvalue distributions", "constants yield reasonable approximations", "gaussian unitary" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1110.0108J" } } }
