On Kedlaya-type inequalities for weighted means

open access: yesJournal of Inequalities and Applications, 2018
In 2016 we proved that for every symmetric, repetition invariant and Jensen concave mean M $\mathscr{M}$ the Kedlaya-type inequality A(x1,M(x1,x2),…,M(x1,…,xn))≤M(x1,A(x1,x2),…,A(x1,…,xn)) $$ \mathscr{A} \bigl(x_{1},\mathscr{M}(x_{1},x_{2}), \ldots ...

Subgaussian concentration inequalities for geometrically ergodic Markov chains [PDF]

open access: yes, 2015
We prove that an irreducible aperiodic Markov chain is geometrically ergodic if and only if any separately bounded functional of the stationary chain satisfies an appropriate subgaussian deviation inequality from its ...

Correlation Between Quadrant Specific Automatic Visual Field Defect and Retinal Nerve Fiber Layer Thickness as Measured by Scanning Laser Polarimetry in Patients With Primary Open Angle Glaucoma

open access: yesKaohsiung Journal of Medical Sciences, 2008
The purpose of this study was to correlate quadrant specific Humphrey visual field mean deviation (MD) with retinal nerve fiber layer (RNFL) thickness as measured by scanning laser polarimetry (GDx), and to determine whether there is a difference in the ...

A New Dispersion Control Chart for Handling the Neutrosophic Data

open access: yesIEEE Access, 2020
The control chart based on mean deviation (MD ) is customary used as a robust alternative to the existing Shewhart control charts for observing changes in dispersion parameter of the process.

Bounds for the generalized ( Φ; f)-mean difference

open access: yesCubo, 2020
In this paper we establish some bounds for the \( (\Phi;f) \)-mean difference introduced in the general settings of measurable spaces and Lebesgue integral, which is a two functions generalization of Gini mean difference that has been widely used by ...

Minimizing weighted mean absolute deviation of job completion times from their weighted mean [PDF]

open access: yes, 2011
Cataloged from PDF version of article.We address a single-machine scheduling problem where the objective is to minimize the weighted mean absolute deviation of job completion times from their weighted mean.

Critical properties of the half-filled Hubbard model in three dimensions [PDF]

open access: yes, 2011
By means of the dynamical vertex approximation (D$\Gamma$A) we include spatial correlations on all length scales beyond the dynamical mean field theory (DMFT) for the half-filled Hubbard model in three dimensions.

Bias-Corrected Root Mean Square Deviation Estimators

open access: yesFoundations
The root mean square deviation (RMSD) is a widely used item fit statistic in item response models. However, the sample RMSD is known to exhibit positive bias in small samples. To address this, seven alternative bias-corrected RMSD estimators are proposed

Monotone Mean Lp-Deviation Risk Measures

open access: yesMathematics, 2023
In this paper, we establish a new coherent risk measure on Lp, which we refer to as the monotone mean Lp-deviation risk measure. Then, the related properties are discussed.

Extremal Lipschitz functions in the deviation inequalities from the mean

open access: yes, 2013
We obtain an optimal deviation from the mean upper bound \begin{equation} D(x)\=\sup_{f\in \F}\mu\{f-\E_{\mu} f\geq x\},\qquad\ \text{for}\ x\in\R\label{abstr} \end{equation} where $\F$ is the class of the integrable, Lipschitz functions on probability ...
