A General Solution for the Errors in Variables (EIV) Model with Equality and Inequality Constraints

open access: yesApplied Sciences, 2022
Targeting the adjustment of the errors-in-variables (EIV) model with equality and inequality constraints, a general solution that is similar to the classical least square adjustment is proposed based on the penalty function and the weight in measurement.

Errors-in-Variables Models [PDF]

open access: yes, 2000
Errors-in-variables (EIV) models axe regression models in which the regres-sors axe observed with errors. These models include the linear EIV models, the nonlinear EIV models, and the partially linear EIV models. Suppose that we want to investigate the relationship between the yield (Y) of corn and available nitrogen (X) in the soil.

The HERBAL Model: A Hierarchical Errors-in-variables Bayesian Lognormal Hurdle Model for Galactic Globular Cluster Populations

open access: yesThe Astrophysical Journal, 2023
Galaxy stellar mass is known to be monotonically related to the size of the galaxy’s globular cluster (GC) population for Milky Way sized and larger galaxies.

Errors in variables in simultaneous equation models [PDF]

open access: yesJournal of Econometrics, 1977
Abstract The simultaneous equation model is considered when errors in variables are present in the exogenous variables. By means of a distributional assumption on the exogenous variables, the system is transformed into an augmented structural model.

Value and limitations of intracranial recordings for validating electric field modeling for transcranial brain stimulation

open access: yesNeuroImage, 2020
Comparing electric field simulations from individualized head models against in-vivo intra-cranial recordings is considered the gold standard for direct validation of computational field modeling for transcranial brain stimulation and brain mapping ...

Estimation of Nonlinear Errors-in-Variables Models

open access: yesThe Annals of Statistics, 1982
An estimation procedure is presented for the coefficients of the nonlinear functional relation, where observations are subject to measurement error. The distributional properties of the estimators are derived, and a consistent estimator of the covariance matrix is given.

Scaled weighted total least-squares adjustment for partial errors-in-variables model

open access: yesJournal of Geodetic Science, 2016
Scaled total least-squares (STLS) unify LS, Data LS, and TLS with a different choice of scaled parameter. The function of the scaled parameter is to balance the effect of random error of coefficient matrix and observation vector for the estimate of ...

Estimation of the mean of the partially linear single-index errors-in-variables model with missing response variables

open access: yesJournal of Inequalities and Applications, 2020
In this paper, we estimate the mean of the partially linear single-index errors-in-variables model with missing response variables. The linear covariate is measured with additive error, therefore missing is not random.

Consistency of the total least squares estimator in the linear errors-in-variables regression

open access: yesModern Stochastics: Theory and Applications, 2018
This paper deals with a homoskedastic errors-in-variables linear regression model and properties of the total least squares (TLS) estimator. We partly revise the consistency results for the TLS estimator previously obtained by the author [18]. We present
