Estimating Smoothness and Optimal Bandwidth for Probability Density Functions

open access: yesStats, 2022
The properties of non-parametric kernel estimators for probability density function from two special classes are investigated. Each class is parametrized with distribution smoothness parameter. One of the classes was introduced by Rosenblatt, another one

Some remarks on the ergodic theorem for $U$-statistics

open access: yesComptes Rendus. Mathématique, 2023
In this note, we investigate the convergence of a $U$-statistic of order two having stationary ergodic data. We will find sufficient conditions for the almost sure and $L^1$ convergence and present some counter-examples showing that the $U$-statistic ...

DAVENPORT SERIES AND ALMOST-SURE CONVERGENCE [PDF]

open access: yesThe Quarterly Journal of Mathematics, 2010
We consider Davenport-like series with coecients in l 2 and discuss L 2 -convergence as well as almost-everywhere convergence. We give an example where both fail to hold. We next improve former sucient conditions under which these convergences are true.

Some Types of Convergence for Negatively Dependent Random Variables under Sublinear Expectations

open access: yesDiscrete Dynamics in Nature and Society, 2019
In this paper, we research complete convergence and almost sure convergence under the sublinear expectations. As applications, we extend some complete and almost sure convergence theorems for weighted sums of negatively dependent random variables from ...

Almost sure convergence of weighted sums [PDF]

open access: yesMiskolc Mathematical Notes, 2013
Summary: Let \(\{X:X_n,\;n\geq 1\}\) be a sequence of identically distributed random variables and \(\{a_{i,n}:\;1\leq i\leq n\}\) be a triangular array of constants. In this short paper, we establish a general almost sure convergence theorem for the weighted sum \(S_n=\sum^n_{i=1} a_{i,n} X_i\). Our results improve those of \textit{S. H.

On the almost sure convergence of sums [PDF]

open access: yesStatistics & Probability Letters, 2021
Two counterexamples, addressing questions raised in \cite{AD} and \cite{PZ}, are provided. Both counterexamples are related to chaoses. Let $F_n=Y_n+Z_n$. It may be that $F_n\overset{a.s.}\longrightarrow 0$, $F_n\overset{L_{2+ }}\longrightarrow 0$ and $E\bigl\{\sup_n\,\abs{F_n}^ \bigr\}0$ and $Y_n$ and $Z_n$ belong to chaoses of uniformly bounded ...

Probabilistic norms and statistical convergence of random variables [PDF]

open access: yesSurveys in Mathematics and its Applications, 2009
The paper extends certain stochastic convergence of sequences of Rk -valued random variables (namely, the convergence in probability, in Lp and almost surely) to the context of E-valued random variables.

Almost Sure Convergence for the Maximum of Nonstationary Random Fields [PDF]

open access: yes, 2015
We obtain an almost sure limit theorem for the maximum of nonstationary random fields under some dependence conditions. The obtained result is applied to Gaussian random fields.

Almost sure convergence of extreme order statistics

open access: yesElectronic Journal of Statistics, 2009
Let $M_n^{(k)}$ denote the $k$th largest maximum of a sample $(X_1,X_2,...,X_n)$ from parent $X$ with continuous distribution. Assume there exist normalizing constants $a_n>0$, $b_n\in \mathbb{R}$ and a nondegenerate distribution $G$ such that $a_n^{-1}(M_n^{(1)}-b_n)\stackrel{w}{\to}G$.
