The Empirical Content of Canonical Models of Infectious Diseases: The Proportional Hazard Specification
研究了传染病异质性混合模型的可证伪含义，发现该模型在子人群的易感生存函数上隐含比例风险约束，并讨论了子人群可观测与不可观测时的可检验约束与模型识别。
This paper discusses the falsifiable implications of the heterogeneous mixing model of infectious disease. It is shown that the model implies a proportional hazard restriction across the set of susceptible survival functions of the subpopulations. Using this implication, the testable restrictions and identification of the model are discussed when subpopulations are observable as well as unobservable.
