Estimation of transmission line parameters by using two least‐squares methods

open access: yesIET Generation, Transmission & Distribution, 2021
This work proposes two new approaches based on the ordinary least‐squares method and the total least‐squares method to estimate the parameters of a balanced three‐phase transmission line using voltage and current measurements from phasor measurement unit.

The Simulation Study to Test the Performance of Quantile Regression Method With Heteroscedastic Error Variance

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2017
The purpose of this article was to describe the ability of the quantile regression method in overcoming the violation of classical assumptions. The classical assumptions that are violated in this study are variations of non-homogeneous error or ...

Ordinary Least Squares: the Adequacy of Linear Regression Solutions under Multicollinearity and without it [PDF]

open access: yesProblemi Ekonomiki, 2019
The article deals with the problem of economic adequacy of solving a linear regression problem by the OLS method. The study uses the following definition of adequacy: a linear regression solution is considered adequate if it not only has correct signs ...

Robust-M new two-parameter estimator for linear regression models: Simulations and applications

open access: yesAfrican Scientific Reports, 2023
In the presence of multicollinearity and outliers, the ordinary least squares estimator remains inconsistent and unreliable. Several estimators have been proposed that can co-handle the problems of multicollinearity and outliers simultaneously.

A Risk Comparison of Ordinary Least Squares vs Ridge Regression [PDF]

open access: yes, 2013
We compare the risk of ridge regression to a simple variant of ordinary least squares, in which one simply projects the data onto a finite dimensional subspace (as specified by a Principal Component Analysis) and then performs an ordinary (un-regularized)

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...
