Alcohol Use and Gamma-Glutamyltransferase Using a Mendelian Randomization Design in the Guangzhou Biobank Cohort Study. [PDF]
PLoS ONE, 2015 Observational studies and small intervention studies suggest alcohol raises gamma-glutamyltransferase (GGT). We used Mendelian randomization to assess the causal effect of alcohol use on GGT in older Chinese people.An instrumental variable (IV) analysis ...

An Edgeworth Expansion for $U$-Statistics
The Annals of Statistics, 1980 It is shown that, under some regularity conditions on the kernel, a one-sample $U$-statistic with kernel of degree two admits an asymptotic expansion with remainder term $o(N^{-1})$.

Asymptotic distributions of degenerated U-statistics
Statistical Theory and Related FieldsA degenerated U-statistic with rank 2 is known to converge in distribution to a weighted sum of independent chi-square random variables. However, a result for the asymptotic distribution of a degenerated U-statistic with rank higher than 2 is not ...

Poisson limits for U-statistics
Stochastic Processes and their Applications, 2002 In the first part of the paper point processes of structure like a \(U\)-statistic with a symmetric non-negative kernel are considered and their convergence to a Poisson process is established under conditions of regularity and asymptotic independence. The result is then utilized to obtain \(\alpha \)-stable limits for \(U\)-statistics with heavy right-

The LIL for U-Statistics in Hilbert Spaces [PDF]
Journal of Theoretical Probability, 2007 We give necessary and sufficient conditions for the (bounded) law of the iterated logarithm for $U$-statistics in Hilbert spaces. As a tool we also develop moment and tail estimates for canonical Hilbert-space valued $U$-statistics of arbitrary order, which are of independent interest.
