Robust Regression with Density Power Divergence: Theory, Comparisons, and Data Analysis

open access: yesEntropy, 2020
Minimum density power divergence estimation provides a general framework for robust statistics, depending on a parameter α , which determines the robustness properties of the method. The usual estimation method is numerical minimization of the power

Tail Behavior of Regression Estimators and their Breakdown Points [PDF]

open access: yesEconometrica, 1990
Following \textit{J. Jurečková} [Ann. Stat. 9, 578-585 (1981; Zbl 0476.62032), and Commentat. Math. Univ. Carol. 22, 365-375 (1981; Zbl 0466.62030)], this paper introduces a finite-sample measure of performance of regression estimators based on tail behaviour.

Breakdown and asymptotic properties of resampled estimates [PDF]

open access: yes, 1995
In this paper we study the breakdown and asymptotic properties of resampled t-estimates. We find that they retain the finite breakdown point of the exact estimator.

Influence of Molecule Structure on Lightning Impulse Breakdown of Ester Liquids

open access: yesEnergies, 2021
Ester liquids are environmentally friendly insulating oils, and they can be used as an alternative to mineral oil in transformers, even though in most countries spills of ester oils must be treated like spills of mineral oil.

Breakdown Pressure Prediction of Tight Sandstone Horizontal Wells Based on the Mechanism Model and Multiple Linear Regression Model

open access: yesEnergies, 2022
Accurately predicting the breakdown pressure in horizontal sections is essential when designing and optimizing fracturing jobs for horizontal wells in tight gas reservoirs.

Comprehensive Definitions of Breakdown Points for Independent and Dependent Observations [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2003
SummaryWe provide a new definition of breakdown in finite samples, with an extension to asymptotic breakdown. Previous definitions centre on defining a critical region for either the parameter or the objective function. If for a particular outlier configuration the critical region is entered, breakdown is said to occur. In contrast with the traditional

The breakdown of magneto-hydrodynamics near AdS2 fixed point and energy diffusion bound

open access: yesJournal of High Energy Physics, 2022
We investigate the breakdown of magneto-hydrodynamics at low temperature (T) with black holes whose extremal geometry is AdS2×R2. The breakdown is identified by the equilibration scales (ω eq , k eq) defined as the collision point between the diffusive ...

Multi-scale fluctuations near a Kondo Breakdown Quantum Critical Point [PDF]

open access: yes, 2008
We study the Kondo-Heisenberg model using a fermionic representation for the localized spins. The mean-field phase diagram exhibits a zero temperature quantum critical point separating a spin liquid phase where the f-conduction hybridization vanishes ...

The Breakdown Process of Hexadecane Films Induced by Quasi-Static Loading

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2007
A novel experimental method has been developed to quantify the breakdown processes of thin oil films induced by quasi-static loading. The method uses a steel-oil-mercury system along with complex impedance analysis, which provides the simultaneous ...
