What's Flu Got To Do With It? The payoff of influenza studies for medical demography.
What's Flu Got To Do With It? The payoff of influenza studies for medical demography. We review some of the major features of influenza mortality in the United States, 1959-2007, the period in which the most detailed data are available. Focus is on two areas, first, classification robustness across influenza and pneumonia over time. Second, we estimate 2-parameter Gompetrz models of winter pneumonia and influenza (P+I) mortality. We find that Gompertz is a good parameterization of P+I mortality
