Weak nondifferential measurement error models
(ELSEVIER SCIENCE BV, 1998)
In this note we consider the class of weak nondifferential measurement error models, which as a special case, contains the class of the nondifferential measurement error models (Carroll et al., 1995). Examples of measurement ...
Hypothesis testing in an errors-in-variables model with heteroscedastic measurement errors
(JOHN WILEY & SONS LTD, 2008)
In many epidemiological studies it is common to resort to regression models relating incidence of a disease and its risk factors. The main goal of this paper is to consider inference on such models with error-prone ...
A multivariate ultrastructural errors-in-variables model with equation error
(ELSEVIER INC, 2011)
This paper deals with asymptotic results on a multivariate ultrastructural errors-in-variables regression model with equation errors Sufficient conditions for attaining consistent estimators for model parameters are presented ...
Effect of measurement error and autocorrelation on the (X)over-bar chart
(Routledge Journals, Taylor & Francis Ltd, 2011-01-01)
Measurement error and autocorrelation often exist in quality control applications. Both have an adverse effect on the (X) over bar chart's performance. To counteract the undesired effect of autocorrelation, we build-up the ...
Bayesian inference for dependent elliptical measurement error models
(ELSEVIER INC, 2010)
In this article we provide a Bayesian analysis for dependent elliptical measurement error models considering nondifferential and differential errors. In both cases we compute posterior distributions for structural parameters ...
Influence Assessment in an Heteroscedastic Errors-in-Variables Model
(TAYLOR & FRANCIS INC, 2012)
The main goal of this article is to consider influence assessment in models with error-prone observations and variances of the measurement errors changing across observations. The techniques enable to identify potential ...
Contribuições em modelos de regressão com erro de medida multiplicativo
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2016-02-04)
In regression models in which a covariate is measured with error, it is common
to use structures that correlate the observed covariate with the true non-observed
covariate. Such structures are usually additive or ...
Inference in multivariate regression models with measurement errors
(2023)
Multivariate regression models are helpful in many fields. However, independent variables (covariates or predictors) could be measured with error. That implies the necessity of considering a new kind of model called ...
Semiparametric Bayesian measurement error modeling
(ELSEVIER INC, 2010)
This work presents a Bayesian semiparametric approach for dealing with regression models where the covariate is measured with error. Given that (1) the error normality assumption is very restrictive, and (2) assuming a ...
