By using a direct and simpler approach, we retreat P. L. Hsu's (1951, J. Chinese Math. Soc., Vol. 1, pp. 257-280) formulas in terms of the characteristic function and provide some new results as well. The case of nonnegative random variables is also investigated through both characteristic function and Laplace-Stieltjes transform. Besides, we prove that the distribution of a nonnegative random variable with a finite fractional moment can be completely determined by a proper subset of the translated fractional moments. This improves significantly Hall's (1983) result for distributions on the right-half line.", "revisions": [ { "version": "v1", "updated": "2018-09-20T03:26:03.000Z" } ], "analyses": { "subjects": [ "60E10", "42A38", "42B10" ], "keywords": [ "characteristic function", "absolute moments", "finite fractional moment", "nonnegative random variable", "probability distributions" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
