The Liu-Type Estimator Based on Parameter Optimization and its Application in SBAS Deformation Model Inversion

open access: yesIEEE Access, 2021
A situation in which an image is combined with multiple images to form interferometric pairs is often observed in small baseline subset-interferometric synthetic aperture radar (SBAS-InSAR) deformation inversion, and this situation leads to a near linear

On the Performance of Principal Component Liu-Type Estimator under the Mean Square Error Criterion [PDF]

open access: yesJournal of Applied Mathematics, 2013
Wu (2013) proposed an estimator, principal component Liu-type estimator, to overcome multicollinearity. This estimator is a general estimator which includes ordinary least squares estimator, principal component regression estimator, ridge estimator, Liu ...

Shifted Liu-Type Estimator in The Linear Regression

open access: yesJurnal Matematika, Statistika dan Komputasi, 2022
The methods to solve the problem of multicollinearity have an important issue in the linear regression. The Liu-type estimator is one of these methods used to reduce its effect. This estimator is an estimator with two parameters denoted  and . Kurnaz and Akay (2015) [6] introduced a new approach for the Liu-type estimator and called it new Liu-type (NL)

Efficiency of the Principal Component Liu-Type Estimator in Logistic Regression

open access: yesRevstat Statistical Journal, 2020
In this paper we propose a principal component Liu-type logistic estimator by combining the principal component logistic regression estimator and Liu-type logistic estimator to overcome the multicollinearity problem. The superiority of the new estimator

A New Liu Type of Estimator for the Restricted SUR Estimator

open access: yesJournal of Modern Applied Statistical Methods, 2020
A new Liu type of estimator for the seemingly unrelated regression (SUR) models is proposed that may be used when estimating the parameters vector in the presence of multicollinearity if the it is suspected to belong to a linear subspace. The dispersion matrices and the mean squared error (MSE) are derived.

The beta Liu-type estimator: simulation and application

open access: yesHacettepe Journal of Mathematics and Statistics, 2023
The Beta Regression Model (BRM) is commonly used while analyzing data where the dependent variable is restricted to the interval $[0,1]$ for example proportion or probability. The Maximum Likelihood Estimator (MLE) is used to estimate the regression coefficients of BRMs.

An almost unbiased Liu-type estimator in the linear regression model

open access: yesCommunications in Statistics - Simulation and Computation, 2022
A biased estimator, compared to least squares estimators, is one of the most used statistical procedures to overcome the problem of multicollinearity. Liu-type estimators, which are biased estimators, are preferred in a wide range of fields. In this article, we propose an almost unbiased Liu-type (AUNL) estimator and discuss its performance under the ...
