The Weibull Marshall–Olkin Lindley distribution: properties and estimation

open access: yesJournal of Taibah University for Science, 2020
We obtain some properties of the Weibull Marshall–Olkin Lindley distribution. Its hazard rate function can be increasing, decreasing, bathtub-shaped, decreasing-increasing-decreasing and unimodal.

Some Limit Behavior of Order Statistics With Variable Ranks [PDF]

open access: yesThe Egyptian Statistical Journal, 1990
In the present investigation we prove that any sequence of order statistics, with nondecreasing variable rank sequence, is mixing in the sense of Renyi.

Logistic Order Statistics

open access: yesThe Annals of Mathematical Statistics, 1963
Expected values and standard deviations of order statistics from a logistic distribution are given for sample sizes $n = 1,2, \cdots, 10$ and $n = 15, 20, 50$, and 100, and summarized in graphs to facilitate interpolation to other sample sizes. For $n \leqq 10$ the results are compared with asymptotic approximations.

A User-Friendly Algorithm for Detecting the Influence of Background Risks on a Model

open access: yesRisks, 2018
Background, or systematic, risks are integral parts of many systems and models in insurance and finance. These risks can, for example, be economic in nature, or they can carry more technical connotations, such as errors or intrusions, which could be ...

THORS: An Efficient Approach for Making Classifiers Cost-Sensitive

open access: yesIEEE Access, 2019
In this paper, we propose an effective THresholding method based on the Order Statistic, called THORS, to convert an arbitrary scoring-type classifier, which can induce a continuous cumulative distribution function of the score, into a cost-sensitive one.

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 ...

A New Family of Truncated Nadarajah-Haghighi-G Properties with Real Data Applications

open access: yesTikrit Journal of Administrative and Economic Sciences, 2023
In this paper, the [0,1] truncated Nadarajah Haghighi- G family is introduced, and some of its statistical properties such as expansion of its PDF are derived. In addition, quantile function, survival function, hazard rate function, reversed hazard rate

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 ...
