What Is Berkson Error


Journal of the American Statistical Association. 45 (250): 164–180. This bias can be reduced by using the mean of multiple measurements in the analysis requiring internal replicates for each individual, or it can be corrected for by using the information This analysis is solely based on the controls (i.e. Fortschritte in der Umweltmedizin.

An example of Berkson error arises in exposure assessment in epidemiological studies. Sinica 10 923–936. Heid, GSF-National Research Center of Environment and Health, Institute of Epidemiology, Ingolstädter Landstr. 1, 85764 Neuherberg, Germany. J., Namboodiri, M.

Measurement error in exposure assessment: an error model and its impact on studies of lung cancer and residential radon exposure in Germany. Modern exposure assessment should therefore not only aim to be as accurate and precise as possible, but should also provide a model of the measurement errors that unavoidably remain with clear On the potential of measurement error to induce differential bias on risk estimates: an example from radon epidemiology.

For multiplicative error, alternatives are: (1) the geometric standard deviation (GSD) of the error, exp(logEM), or (2) the coefficient of variation (CV) defined (a) as the error's SD on the original Export citationFormat:Text (BibTeX)Text (printer-friendly)RIS (EndNote, ProCite, Reference Manager)Delivery Method:Download Email Please enter a valid email address.Email sent.

An estimate of both errors combined is derived from by the SD of the residuals. For example, extending the definition of the predictor from "residential radon exposure" to "lung dose" induces Berkson error and does not attenuate the risk estimate.To assume the sum of both error For additive error, if error and true predictor are fairly normally distributed, 95% of the observed values lie within [x-2EA,x+2EA].
