Goodness-of-fit test in a multivariate errors-in-variables model AX=B [PDF]

open access: yesModern Stochastics: Theory and Applications, 2016
We consider a multivariable functional errors-in-variables model $AX\approx B$, where the data matrices A and B are observed with errors, and a matrix parameter X is to be estimated.

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

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.

Multivariate adaptive regression spline modeling for estimating carotid artery plaque thickness in Chinese men with type 2 diabetes [PDF]

open access: yesJournal of International Medical Research
Objective The incidence of type 2 diabetes continues to increase worldwide, with cardiovascular disease as the leading cause of mortality in this population. Carotid artery plaque thickness serves as a non-invasive marker of atherosclerosis.

Fitting an Equation to Data Impartially

open access: yesMathematics, 2023
We consider the problem of fitting a relationship (e.g., a potential scientific law) to data involving multiple variables. Ordinary (least squares) regression is not suitable for this because the estimated relationship will differ according to which ...

Multivariate Sea Surface Prediction in the Bohai Sea Using a Data-Driven Model

open access: yesJournal of Marine Science and Engineering, 2023
Data-driven predictions of marine environmental variables are typically focused on single variables. However, in real marine environments, there are correlations among different oceanic variables.

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.

K-Nearest Neighbor Method with Principal Component Analysis for Functional Nonparametric Regression

open access: yesمجلة بغداد للعلوم, 2022
This paper proposed a new  method to study functional non-parametric regression data analysis with conditional expectation in the case that the covariates  are functional and the Principal Component Analysis was utilized to de-correlate the multivariate

Adjusted Likelihood Inference in an Elliptical Multivariate Errors-in-Variables Model [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2014
In this paper we obtain an adjusted version of the likelihood ratio test for errors-in-variables multivariate linear regression models. The error terms are allowed to follow a multivariate distribution in the class of the elliptical distributions, which has the multivariate normal distribution as a special case.
