Weak nondifferential measurement error models

Abstract

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 error models which are in this class and that are not nondifferential models are considered. Only simple linear regression models are used to illustrate the approach but as indicated it can be generalized to more complex situations. Some characterization results are also reported.
