Nonparametric correction for covariate measurement error in a stratified Cox model.
Stratified Cox regression models with large number of strata and small stratum size are useful in many settings, including matched case-control family studies. In the presence of measurement error in covariates and a large number of strata, we show that extensions of existing methods fail either to reduce the bias or to correct the bias under nonsymmetric distributions of the true covariate or ...
متن کاملCorrection for covariate measurement error in nonparametric regression
Many areas of applied statistics have become aware of the problem of measurement error-prone variables and their appropriate analysis. Simply ignoring the error in the analysis usually leads to biased estimates, like e.g. in the regression with error-prone covariates. While this problem has been discussed at length for parametric regression, only few methods exist to handle nonparametric regres...
متن کاملCorrecting for covariate measurement error in logistic regression using nonparametric maximum likelihood estimation
When covariates are measured with error, inference based on conventional generalized linear models can yield biased estimatesof regressionparameters. This problem can potentiallybe rectied byusing generalizedlinear latent and mixedmodels (GLLAMM), including a measurementmodel for the relationship between observed and true covariates. However, the models are typically estimated under the assump...
متن کاملPolynomial regression with normal covariate measurement error
This paper derives the exact functional form of an error contaminated regression function when the error free regression is a polynomial function of error free covariates (discrete or continuous) which are contaminated by normally distributed measurement error, with coe¢cients which may be arbitrary functions of error free covariates. The form of higher order central moment error contaminated r...
متن کاملSurvival Analysis With Heterogeneous Covariate Measurement Error
This article is motivated by a time-to-event analysis where the covariate of interest was measured at the wrong time. We show that the problem can be formulated as a special case of survival analysis with heterogeneous covariate measurement error and develop a general analytic framework. We study the asymptotic behavior of the naive partial likelihood estimates and analytically demonstrate that...
