Inference and other aspects for q−Weibull distribution via generalized order statistics with applications to medical datasets

AIMS Mathematics
This work utilizes generalized order statistics (GOSs) to study the $ q $-Weibull distribution from several statistical perspectives. First, we explain how to obtain the maximum likelihood estimates (MLEs) and utilize Bayesian techniques to estimate the ...

Residual and Past Entropy for Concomitants of Ordered Random Variables of Morgenstern Family

Journal of Probability and Statistics, 2015
For a system, which is observed at time t, the residual and past entropies measure the uncertainty about the remaining and the past life of the distribution, respectively.

The Geometry of (Super) Conformal Quantum Mechanics [PDF]

, 1999
N-particle quantum mechanics described by a sigma model with an N-dimensional target space with torsion is considered. It is shown that an SL(2,R) conformal symmetry exists if and only if the geometry admits a homothetic Killing vector $D^a$ whose ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Weighted extropy measures in general Morgenstern family under k-record values with application to medical data

AIP Advances
In this paper, we study the marginal distribution of concomitants of k-record (KR) values from generalized Farlie–Gumbel–Morgenstern (GFGM) of bivariate distributions. In addition, the joint distribution of concomitants of KR for this family is obtained.

The bivariate Weibull distribution based on the GFGM copula

AIMS Mathematics
In statistical modeling, bivariate models are essential, especially when examining data with two associated variables. Bivariate distributions capture dependencies between variables, offering a more realistic depiction of real-world phenomena compared to

The Exact Joint Distribution of Concomitants of Order Statistics and Their Order Statistics under Normality

Revstat Statistical Journal, 2013
In this work we derive the exact joint distribution of a linear combination of concomitants of order statistics and linear combinations of their order statistics in a multivariate normal distribution.

Initial data sets for the Schwarzschild spacetime

, 2006
A characterisation of initial data sets for the Schwarzschild spacetime is provided. This characterisation is obtained by performing a 3+1 decomposition of a certain invariant characterisation of the Schwarzschild spacetime given in terms of concomitants

Determination of water in organic solvents by flow-injection analysis with Karl Fischer reagent and a biamperometric detection system [PDF]

, 1988
A flow-injection system with a biamperometric flow-through detector provided with two platinum plate electrodes was tested for the determination of water with a two-component pyridine-free Karl Fischer reagent.
