Sample size requirements for epidemiologic studies are usually determined on the basis of the desired level of statistical power. Suppose, however, that one is planning a study in which the participants' true exposure levels are unobservable. Instead, the analysis will be based on an imprecise surro
The ascertainment of probands according to place of residence in hospitals or in the community has enabled our sampling to be representative of whole subpopulations of patients. Probands from psychiatric hospitals are characterized by biased clinical parameters. Our sampling procedure provides impor
