Orthogonal decomposition of finite population L-statistics

Lietuvos Matematikos Rinkinys, 2009
In this paper we study orthogonal decomposition of finite population L-statistics. We propose quite simple form of first two terms of such decomposition.

Estimation of parameters of finite population L-statistics

Nonlinear Analysis, 2013
We consider the estimation of important parameters of a linear combination of order statistics (L-statistic) in a finite population, emphasizing the influence of auxiliary information on the estimation accuracy.

Prediction of Graft Survival Post-liver Transplantation by L-GrAFT Risk Score Model, EASE Score, MEAF Scoring, and EAD

Frontiers in Surgery, 2021
Background: Early allograft dysfunction (EAD) is correlated with poor patient or graft survival in liver transplantation. However, the power of distinct definitions of EAD in prediction of graft survival is unclear.Methods: This retrospective, single ...

Effect of probiotic and Moringa oleifera extract on performance, carcass yield, and mortality of Peking duck [PDF]

Veterinary World, 2022
Background and Aim: Antibiotics have been used as growth promoters in poultry. However, continuous and long-term antibiotics can cause resistance, suppress the immune system, and accumulate toxic residue.

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

Comptes 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 ...

Fixed effects modelling for provider mortality outcomes: Analysis of the Australia and New Zealand Intensive Care Society (ANZICS) Adult Patient Data-base. [PDF]

PLoS ONE, 2014
BackgroundRisk adjusted mortality for intensive care units (ICU) is usually estimated via logistic regression. Random effects (RE) or hierarchical models have been advocated to estimate provider risk-adjusted mortality on the basis that standard ...

A Differential for L-Statistics. [PDF]

The Annals of Statistics, 1977
Abstract : The asymptotic normality result is competitive with one closely related statistic S sub n = Sum from i=(1 to n) of (c wiggle sub in)(X sub in) obtained under stronger conditions on J but a slightly milder condition on F. However, in addition to asymptotic normality of T(F sub n), the differential approach of the present paper yields ...

Bootstrap, jackknife and Edgeworth approximations for finite population L-statistics

Lietuvos Matematikos Rinkinys, 2010
In this paper we give exact bootstrap estimators for the parameters defining one-term Edgeworth expansion of distribution function of finite population L-statistic and compare these estimators with corresponding jackknife estimators. We also compare `````
