Quantum U-statistics [PDF]

open access: yesJournal of Mathematical Physics, 2010
The notion of a U-statistic for an n-tuple of identical quantum systems is introduced in analogy to the classical (commutative) case: given a self-adjoint “kernel” K acting on (Cd)⊗r with r<n, we define the symmetric operator Un=(nr)∑βK(β) with K(β) being the kernel acting on the subset β of {1,…,n}.

The LIL for canonical U-statistics

open access: yesThe Annals of Probability, 2008
We give necessary and sufficient conditions for the (bounded) law of the iterated logarithm for canonical $U$-statistics of arbitrary order $d$, extending the previously known results for $d=2$. The nasc's are expressed as growth conditions on a parameterized family of norms associated with the $U$-statistics kernel.

The LIL for U-Statistics in Hilbert Spaces [PDF]

open access: yesJournal 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.

U-Statistics in Stochastic Geometry [PDF]

open access: yes, 2016
This survey will appear as a chapter of the forthcoming book [19]. A U-statistic of order $k$ with kernel $f:\X^k \to \R^d$ over a Poisson process is defined in \cite{ReiSch11} as$$ \sum\_{x\_1, \dots , x\_k \in ^k\_{\neq}} f(x\_1, \dots, x\_k) $$ under appropriate integrability assumptions on $f$.

Statistical treatment of nuclear counting results [PDF]

open access: yesNuclear Technology and Radiation Protection, 2011
Since the exact time a specific nucleus undergoes radioactive decay cannot be specified, nor can showers caused by secondary cosmic rays be predicted, statistical laws play an important role in almost all cases of experimental nuclear physics.

A comparative study of the Gini coefficient estimators based on the linearization and U-statistics Methods

open access: yesRevista Colombiana de Estadística, 2017
In this paper, we consider two well-known methods for analysis of the Gini index, which are U-statistics and linearization for some income distributions.

A systematic review of the usage of flow diagram in cluster randomized trials [PDF]

open access: yesPraxis Medica, 2014
Flow diagram represent an integral part of consolidated standards of reporting trials (CONSORT). Its use in reporting cluster randomization trials is highly recommended.

Bootstrap for U-Statistics: A new approach [PDF]

open access: yes, 2015
Bootstrap for nonlinear statistics like U-statistics of dependent data has been studied by several authors. This is typically done by producing a bootstrap version of the sample and plugging it into the statistic.
