M-estimation in high-dimensional linear model

open access: yesJournal of Inequalities and Applications, 2018
We mainly study the M-estimation method for the high-dimensional linear regression model and discuss the properties of the M-estimator when the penalty term is a local linear approximation. In fact, the M-estimation method is a framework which covers the

JMASM42: An Alternative Algorithm and Programming Implementation for Least Absolute Deviation Estimator of the Linear Regression Models (R) [PDF]

open access: yes, 2016
We propose a least absolute deviation estimation method that produced a least absolute deviation estimator of parameter of the linear regression model.

Color image segmentation based on intensity and hue clustering - a comparison of LS and LAD approaches

open access: yesCroatian Operational Research Review, 2014
Motivated by the method for color image segmentation based on intensity and hue clustering proposed in [26] we give some theoretical explanations for this method that directly follows from the natural connection between the maximum likelihood approach ...

Least absolute deviation estimation for unit root processes with garch errors [PDF]

open access: yes, 2009
This paper considers a local least absolute deviation estimation for unit root processes with generalized autoregressive conditional heteroskedastic (GARCH) errors and derives its asymptotic properties under only finite second-order moment for both ...

A Maximum Likelihood Approach to Least Absolute Deviation Regression

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
Least absolute deviation (LAD) regression is an important tool used in numerous applications throughout science and engineering, mainly due to the intrinsic robust characteristics of LAD.

Sparse Normalized Least Mean Absolute Deviation Algorithm Based on Unbiasedness Criterion for System Identification With Noisy Input

open access: yesIEEE Access, 2018
In order to solve the system identification problems, the normalized least mean absolute deviation (NLMAD) algorithm was developed as an effective and robust method. In this paper, aiming at the system identification problems with sparsity characteristic,

Forecasting fiscal variables in selected European economies using least absolute deviation method

open access: yesInternational Journal of Engineering Business Management, 2018
Actual economic crisis initiated numerous debates on fiscal policy of the European Union (EU) and unrealistic convergence demands placed upon the Member States, where the emphasis is on fiscal criteria: The budget deficit should not exceed 3% of Gross ...

Proposing Robust LAD-Atan Penalty of Regression Model Estimation for High Dimensional Data

open access: yesمجلة بغداد للعلوم, 2020
The issue of penalized regression model has received considerable critical attention to variable selection. It plays an essential role in dealing with high dimensional data.

PERBANDINGAN METODE MCD-BOOTSTRAP DAN LAD-BOOTSTRAP DALAM MENGATASI PENGARUH PENCILAN PADA ANALISIS REGRESI LINEAR BERGANDA

open access: yesE-Jurnal Matematika, 2017
Outliers are observations that are far away from other observations. Outlier can be interfered with the process of data analysis which influence the regression parameters estimation.
