A measurement error model is a regression model with (substantial) measurement errors in the variables. Disregarding these measurement errors in estimating the regression parameters results in asymptotically biased estimators. Several methods have been proposed to eliminate, or at least to...

Participation in social programs is often misreported in survey data, complicating the estimation of the effects of those programs. In this paper, we propose a model to estimate treatment effects under endogenous participation and endogenous misreporting. We show that failure to account for...

Abstract The problem of misclassification is common in epidemiological and clinical research. In some cases …, misclassification may be incurred when measuring both exposure and outcome variables. It is well known that validity of analytic results … elucidate extensions of well-studied methods in order to facilitate misclassification adjustment when a binary outcome and …

When the exposure is subject to misclassification, the effects estimated can be severely … estimates in the presence of conditional non-differential misclassification of a binary exposure. We show that in the absence of … interaction, the misclassification of the exposure will bias the direct effect towards the null but can bias the indirect effect …

The demand of scientists for confidential micro data from official sources has created discussion of how to anonymize these data in such a way that they can be given to the scientific community. We report results from a German project which exploits various options of anonymization for producing...

Most epidemiological studies suffer from misclassification in the response and/or the covariates. Since ignoring … misclassification induces bias on the parameter estimates, correction for such errors is important. For measurement error, the … continuous analog to misclassification, a general approach for bias correction is the SIMEX (simulation extrapolation) originally …

Consider an observed binary regressor D and an unobserved binary variable D*, both of which affect some other variable Y. This paper considers nonparametric identification and estimation of the effect of D on Y , conditioning on D* = 0. For example, suppose Y is a person's wage, the unobserved D...
