Two-Parameter Modified Ridge-Type M-Estimator for Linear Regression Model [PDF]

open access: yesThe Scientific World Journal, 2020
The general linear regression model has been one of the most frequently used models over the years, with the ordinary least squares estimator (OLS) used to estimate its parameter.

A redescending M-estimator approach for outlier-resilient modeling [PDF]

open access: yesScientific Reports
The OLS model is built on the assumption of normality in the distribution of error terms. However, this assumption can be easily violated, especially when there are outliers in the data.

On the M-Estimator under Third Moment Condition

open access: yesMathematics, 2022
Estimating the expected value of a random variable by data-driven methods is one of the most fundamental problems in statistics. In this study, we present an extension of Olivier Catoni’s classical M-estimators of the empirical mean, which focus on the ...

Combating outliers and multicollinearity in linear regression model using robust Kibria-Lukman mixed with principal component estimator, simulation and computation

open access: yesScientific African, 2023
Scholars usually adopt the method of least squared to model the relationship between a response variable and two or more explanatory variables. Ordinary least squares estimator's performance is good when there is no outliers and multicollinearity in the ...

Robust modified jackknife ridge estimator for the Poisson regression model with multicollinearity and outliers

open access: yesScientific African, 2022
The parameters in the Poisson regression model are usually estimated using the maximum likelihood estimator (MLE). MLE suffers a breakdown when there is either multicollinearity or outliers in the Poisson regression model.

A Least Squares Estimator for Gradual Change-Point in Time Series with m-Asymptotically Almost Negatively Associated Errors

open access: yesAxioms, 2023
As a new member of the NA (negative associated) family, the m-AANA (m-asymptotically almost negatively associated) sequence has many statistical properties that have not been developed. This paper mainly studies its properties in the gradual change point

Asymptotic properties of M-estimator for GARCH(1, 1) model parameters

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
GARCH(1,  1) model is used for analysis and forecasting of financial and economic time series. In the classical version, the maximum likelihood method is used to estimate the model parameters. However, this method is not convenient for analysis of models

Jackknife Kibria-Lukman M-Estimator: Simulation and Application

open access: yesJournal of Nigerian Society of Physical Sciences, 2022
The ordinary least square (OLS) method is very efficient in estimating the regression parameters in a linear regression model under classical assumptions.

Employing Robust MM-estimators in Estimating Principal Component Regression Model - A Comparative Study [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2021
This paper focuses on proposing the use of robust MM estimators in estimating the parameters of the principal component regression model, which is usually used in estimating the regression model when the explanatory variables are not independent.
