WebJun 18, 2024 · Bounding Bias Due to Selection Published 18 June 2024 When epidemiologic studies are conducted in a subset of the population, selection bias can threaten the validity of causal inference. This bias can occur whether or not that selected population is the target population and can occur even in the absence of … WebTo quantify the possible size of this bias, consider the ratio of the observable odds ratio from case-control data to the odds ratio that would have been estimated had the entire cohort been sampled. Assume then that any bias from the case-control study is due to this selection. We therefore have: bias = ˆ Pr(Y = 1 jA = 1;S = 1;c) Pr(Y = 0 jA ...
