Statistical inference for partially linear errors-in-variables panel data models with fixed effects

open access: yesSystems Science & Control Engineering, 2021
In this paper, we consider the statistical inference for the partially linear panel data models with fixed effects. We focus on the case where some covariates are measured with additive errors. We propose a modified profile least squares estimator of the

Prediction in polynomial errors-in-variables models

open access: yesModern Stochastics: Theory and Applications, 2020
A multivariate errors-in-variables (EIV) model with an intercept term, and a polynomial EIV model are considered. Focus is made on a structural homoskedastic case, where vectors of covariates are i.i.d. and measurement errors are i.i.d. as well.

Minimax Rates of p-Losses for High-Dimensional Linear Errors-in-Variables Models over q-Balls

open access: yesEntropy, 2021
In this paper, the high-dimensional linear regression model is considered, where the covariates are measured with additive noise. Different from most of the other methods, which are based on the assumption that the true covariates are fully obtained ...

Estimation in a linear errors-in-variables model under a mixture of classical and Berkson errors

open access: yesModern Stochastics: Theory and Applications, 2021
A linear structural regression model is studied, where the covariate is observed with a mixture of the classical and Berkson measurement errors. Both variances of the classical and Berkson errors are assumed known.

Testing straightness of line objects using total least squares [PDF]

open access: yesTehnika, 2017
The paper presents the adaptation (fitting) of a set of points, with an estimated two-dimensional positions, to the straight line model of the by the application of the Weighted Total Least Squares, WTLS.

Two models for linear comparative calibration [PDF]

open access: yesInternational Journal of Metrology and Quality Engineering, 2012
We consider the comparative calibration problem in the case when linear relationship is assumed between two considered measuring devices with possibly different units and precisions.

An Overview of Linear Structural Models in Errors in Variables Regression

open access: yesRevstat Statistical Journal, 2010
This paper aims to overview the numerous approaches that have been developed to estimate the parameters of the linear structural model. The linear structural model is an example of an errors in variables model, or measurement error model that has wide ...

Beta regression model nonlinear in the parameters with additive measurement errors in variables.

open access: yesPLoS ONE, 2021
We propose in this paper a general class of nonlinear beta regression models with measurement errors. The motivation for proposing this model arose from a real problem we shall discuss here. The application concerns a usual oil refinery process where the

Total Least-Squares Collocation: An Optimal Estimation Technique for the EIV-Model with Prior Information

open access: yesMathematics, 2020
In regression analysis, oftentimes a linear (or linearized) Gauss-Markov Model (GMM) is used to describe the relationship between certain unknown parameters and measurements taken to learn about them.

Asymptotic normality of total least squares estimator in a multivariate errors-in-variables model AX=B

open access: yesModern Stochastics: Theory and Applications, 2016
We consider a multivariate functional measurement error model $AX\approx B$. The errors in $[A,B]$ are uncorrelated, row-wise independent, and have equal (unknown) variances.
