Strong Consistency of $K$-Means Clustering

open access: yesThe Annals of Statistics, 1981
A random sample is divided into the $k$ clusters that minimise the within cluster sum of squares. Conditions are found that ensure the almost sure convergence, as the sample size increases, of the set of means of the $k$ clusters. The result is proved for a more general clustering criterion.

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Strong laws for weighted sums of widely orthant dependent random variables and applications

open access: yesOpen Mathematics
In this study, the strong law of large numbers and the convergence rate for weighted sums of non-identically distributed widely orthant dependent random variables are established.

Asymptotic properties of Kaplan–Meier estimator and hazard estimator for censored survival time with LENQD data

open access: yesStatistical Theory and Related Fields
In this paper, we consider the estimators of distribution function and hazard rate for censored survival time. First, some properties and inequalities are established for linearly extended negative quadrant-dependent sequence as auxiliary results.

Quasi-maximum likelihood estimator of Laplace (1, 1) for GARCH models

open access: yesOpen Mathematics, 2017
This paper studies the quasi-maximum likelihood estimator (QMLE) for the generalized autoregressive conditional heteroscedastic (GARCH) model based on the Laplace (1,1) residuals.

Strong consistency of regression function estimator with martingale difference errors

open access: yesOpen Mathematics, 2021
In this paper, we consider the regression model with fixed design: Yi=g(xi)+εi{Y}_{i}=g\left({x}_{i})+{\varepsilon }_{i}, 1≤i≤n1\le i\le n, where {xi}\left\{{x}_{i}\right\} are the nonrandom design points, and {εi}\left\{{\varepsilon }_{i}\right\} is a ...

Multidirectional Replication for Supporting Strong Consistency, Low Latency, and High Throughput

open access: yesAlexandria Engineering Journal, 2022
Many replication protocols, which can be used in various distributed applications such as distributed databases, collaborative applications, and distributed agenda, sacrifice strong consistency to achieve lower latency and higher throughput.

Parent‐to‐Child Information Disclosure in Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Consistency of the Priestley–Chao estimator in nonparametric regression model with widely orthant dependent errors

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we establish the strong consistency and complete consistency of the Priestley–Chao estimator in nonparametric regression model with widely orthant dependent errors under some general conditions.
