The LIL for canonical U-statistics of order 2 [PDF]
, 2001 Let X,X_1,X_2,... be independent identically distributed random variables and let h(x,y)=h(y,x) be a measurable function of two variables.

Necessary and sufficient conditions for the strong law of large numbers for U-statistics [PDF]
, 2000 Under some mild regularity on the normalizing sequence, we obtain necessary and sufficient conditions for the Strong Law of Large Numbers for (symmetrized) U-statistics. We also obtain nasc's for the a.s.

A new method for determining geochemical anomalies: U-N and U-A fractal models [PDF]
International Journal of Mining and Geo-Engineering, 2022 Undoubtedly, determining the threshold of anomalies and separating geochemical anomalies from background is one of the most important stages of minerals exploration.

Efficient Aggregated Kernel Tests using Incomplete U-statistics [PDF]
Neural Information Processing Systems, 2022 We propose a series of computationally efficient nonparametric tests for the two-sample, independence, and goodness-of-fit problems, using the Maximum Mean Discrepancy (MMD), Hilbert Schmidt Independence Criterion (HSIC), and Kernel Stein Discrepancy ...

U-statistics of growing order and sub-Gaussian mean estimators with sharp constants [PDF]
Mathematical Statistics and Learning, 2022 This paper addresses the following question: given a sample of i.i.d. random variables with finite variance, can one construct an estimator of the unknown mean that performs nearly as well as if the data were normally distributed? One of the most popular

Robust change-point detection for functional time series based on U-statistics and dependent wild bootstrap [PDF]
Statistical Papers, 2022 The aim of this paper is to develop a change-point test for functional time series that uses the full functional information and is less sensitive to outliers compared to the classical CUSUM test. For this aim, the Wilcoxon two-sample test is generalized

Tail inference using extreme U-statistics [PDF]
Electronic Journal of Statistics, 2022 Extreme U-statistics arise when the kernel of a U-statistic has a high degree but depends only on its arguments through a small number of top order statistics.

Graphs defined on groups [PDF]
International Journal of Group Theory, 2022 This paper concerns aspects of various graphs whose vertex set is a group $G$ and whose edges reflect group structure in some way (so that, in particular, they are invariant under the action of the automorphism group of $G$).
