Berry Esseen type bounds to the normal, based on approximate zero bias couplings and approximate $\\lambda,R$-Stein pairs, are obtained using Stein's method. The bounds are then applied to combinatorial central limit theorems where the random permutation has the Ewens $\\mathcal{E}_\\theta$ distribution with $\\theta>0$ which can be specialized to the uniform distribution by letting $\\theta=1$. The family of the Ewens distributions appears in the context of population genetics in biology.", "revisions": [ { "version": "v1", "updated": "2017-07-12T05:32:08.000Z" } ], "analyses": { "subjects": [ "60F05", "60C05" ], "keywords": [ "approximate zero bias couplings", "combinatorial central limit theorems", "steins method", "ewens distribution", "stein pair" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
