On the Completeness of Order Statistics

open access: yesThe Annals of Mathematical Statistics, 1960
Let $X_1, X_2, \cdots, X_n$ be a sample of a one-dimensional random variable $X$; let the order statistic $T(X_1, X_2, \cdots, X_n)$ be defined in such a manner that $T(x_1, x_2, \cdots, x_n) = (x^{(1)}, x^{(2)}, \cdots, x^{(n)})$ where $x^{(1)} \leqq x^{(2)} \leqq \cdots \leqq x^{(n)}$ denote the ordered $x's$; and let $\Omega$ be a class of one ...

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 ...

A generalisation of the exponential distribution and its applications on modelling skewed data

open access: yesStatistical Theory and Related Fields, 2018
In this paper, a generalisation of the exponential distribution, namely, Weibull exponentiated-exponential (WEE) distribution, is proposed. The shapes of the density function possess great flexibility.

On $q$-Order Statistics

open access: yes, 2023
Building on the notion of $q$-integral introduced by Thomae in 1869, we introduce $q$-order statistics (that, is $q$-analogues of the classical order statistics, for ...

Excess Lifetime Extropy of Order Statistics

open access: yesAxioms, 2023
This paper explores the concept of residual extropy as an uncertainty measure for order statistics. We specifically derive the residual extropy for the ith-order statistic and establish its relationship with the residual extropy of the ith-order ...

A scale-free adaptive statistic for testing exponentiality against Weibull and generalized Pareto distributions [PDF]

open access: yes, 2007
In Fortiana and Grané (2002) we study a scale-free statistic, based on Hoeffding's maximum correlation, for testing exponentiality. This statistic admits an expansion along a countable set of orthogonal axes, originating a sequence of statistics ...

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.

The W Test of Uniformity (Complete Sample). [PDF]

open access: yesThe Egyptian Statistical Journal, 1999
This research work is concerned with deriving a test statistic for testing the null hypothesis that a complete random sample was drain from a uniform distribution with unknown parameters.

Functions of Order Statistics

open access: yesThe Annals of Mathematical Statistics, 1972
Two theorems on the asymptotic normality of linear combinations of functions of order statistics are given. Theorem 1 requires a "smooth" scoring function but the underlying df need not be continuous even and can also depend on the sample size. Theorem 2 allows general scoring functions but places additional restrictions on the df.
