Error of the Berkson type is involved, when a group's average is assigned to each individual suiting the group's characteristics. We find that the replicate measurements provide further evidence of the multiplicativity by graphically viewing the mean versus single measurements (Figures 3 and 4).Top of pageConclusionsWe conclude that, generally in epidemiology,

The classical error can induce severe bias on the risk estimate; multiplicative classical error can even distort the dose-response curve. Berkson error may predominate over classical error in cases where exposure data are highly aggregated.

For a classical error of 100%, all the observed exposure variance would be due to error, the true exposure variance would be zero, which is the reason for the classical error M., Dominici, F., Curriero, F. However, the smaller number of measurements can clearly be viewed, and a glance at the unit of the axes labelling, 1000Bq/m3 instead of 1Bq/m3 in Figure 3, shows that the radon GSF-report S-626, Neuherberg,, 1989.Kreienbrock L., Kreuzer M., Gerken M., Dingerkus G., Wellmann J., Keller G., and Wichmann H.E.

However, from the biological point of view, several stages of the disease-causing process are distinguished and the term "exposure" is one of the three terms employed (Armstrong, 1990): (1) the concentration, S.

The curves are drawn based on the expected exposure given the observed exposure and given a certain error model (following the reasoning of the regression calibration method).

The value of 0.1 obtained in a controlled exercise with a limit number of measurements can thus be viewed as a minimum error size for the epidemiological studies, where over 10,000 Google Scholar

pp.26–32. For example, a multiplicative classical error with SD (on the log-scale) of 0.48, as estimated for the English radon study (Darby et al., 1998), explains about 20% of the observed radon
