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 $f$.

U-statistic based on overlapping sample spacings [PDF]

open access: green, 2022
For testing goodness of fit, we consider a class of U-statistics of overlapping spacings of order two, and investigate their asymptotic properties.

Two-Sample U-Statistic Processes for Long-Range Dependent Data [PDF]

open access: green, 2014
Motivated by some common-change point tests, we investigate the asymptotic distribution of the U-statistic process $U_n(t)=\sum_{i=1}^{[nt]}\sum_{j=[nt]+1}^n h(X_i,X_j)$, $0\leq t\leq 1$, when the underlying data are long-range dependent.

The abstract of doctoral dissertation ‘Some research on hypothesis testing and nonparametric variable screening problems for high dimensional data’

open access: yesStatistical Theory and Related Fields, 2020
In this thesis, we construct test statistic for association test and independence test in high dimension, respectively, and study the corresponding theoretical properties under some regularity conditions.

Reliability Class Testing and Hypothesis Specification: NBRULC−t Characterizations with Applications for Medical and Engineering Data Modeling

open access: yesAxioms, 2023
Due to the complexity of the data being generated day in and day out in many practical domains, as a result of the development of scales for rating the success or failure of reliability, a new domain of reliability called the classes of life and ...

IMPROVEMEnTS In ASSESSInG THE FORECASTS ACCURACY - A CASE STUDY FOR ROMAnIAn MACROECOnOMIC FORECASTS [PDF]

open access: yesSerbian Journal of Management, 2013
The objective of this study is to introduce new forecasts’ accuracy measures for two types of predictions: point forecasts (radical of order n of the mean of squared errors, mean for the differencebetween each predicted value and the mean of the ...

Some laws of a system with a constant amount of energy [PDF]

open access: yesScience of Sintering, 2008
In this paper, different relationships and functional dependences of a system with a constant energy U=const., have been analyzed. The combinatorial nature of this analysis enables the conclusion that a family of entropy curves i.e.

Kaplan-Meier V- and U-statistics [PDF]

open access: yesElectronic Journal of Statistics, 2020
In this paper, we study Kaplan-Meier V- and U-statistics respectively defined as $θ(\widehat{F}_n)=\sum_{i,j}K(X_{[i:n]},X_{[j:n]})W_iW_j$ and $θ_U(\widehat{F}_n)=\sum_{i\neq j}K(X_{[i:n]},X_{[j:n]})W_iW_j/\sum_{i\neq j}W_iW_j$, where $\widehat{F}_n$ is the Kaplan-Meier estimator, $\{W_1,\ldots,W_n\}$ are the Kaplan-Meier weights and $K:(0,\infty)^2\to\

New classes at Specific Age: Properties and Testing hypotheses [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2013
In this article we introduce new classes of life distributions namely new better (worse) than used in expectation at specific age t0 NBUE-t0 (NWUE-t0) and harmonic new better (worse) than used in expectation at specific age t0 HNBUE-t0 (HNWUE-t0).
