AbstractThe assessment of errors of measurement and their effects needs to take into account the structure of the data in which the errors occur. This is illustrated and the appropriate analysis of variance specified for a variety of contexts.

Toxicology and Industrial Health, 1990
Errors in exposure measures reduce the power in statistical tests in health effect studies, and also bias the estimate of the magnitude of the effect of exposure on health. Several types of error in commonly used exposure measures are described. To study how these errors in exposure measures may obscure exposure-response relationships, an imaginary ...

Abstract A certain amount of error is intrinsic to any measurement process. In the conduct of epidemiologic research, measurement error is potentially a major problem that may invalidate the results of otherwise well-designed studies. For instance, if a case-control study is undertaken to address the issue of whether past dietary fat ...

AbstractA main objective of the chapter is to demonstrate how measurement error problems which are non-tractable in cross-section data can be overcome when (balanced) panel data are available. Transformations (including differences) recommended to eliminate fixed effects, can, in measurement error situations, magnify the relative noise–signal variation.
