"Statistical models are sometimes misunderstood in epidemiology. Statistical models for data are never true. The question of whether a model is true is irrelevant. A more appropriate question is whether we obtain the correct scientific conclusion if we pretend that the process under study behaves according to a particular statistical model."
Scott L. Zeger, American Journal of Epidemiology 1991, 134 (10), 1062. Courtesy of William Fisher
