Based on this sample, we establish a central limit theorem for U-statistics with monotonic kernels of degree 3 and above using the Hoeffding's decomposition. We also extend these results to U-statistics based on non-monotonic functions. We also obtain a consistent estimator of $\\sigma_f$, where $\\sigma_f^2 = \\underset{n \\to \\infty}{lim}(Var S_n)/n$, $S_n = \\sum_{j=1}^n f(X_j)$, and $f$ is a non-monotonic function, using the ideas of Peligrad and Suresh $(1995)$.", "revisions": [ { "version": "v1", "updated": "2014-11-12T06:20:43.000Z" } ], "analyses": { "keywords": [ "limiting distribution", "u-statistics", "non-monotonic function", "stationary associated random variables", "central limit theorem" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1411.3083G" } } }
