Modeling Influenza-Like Illness Activity in the United States

Influenza causes yearly costs for hospitalization and outpatient visits of more than $10 billion in the US. The prediction of influenza epidemics is thus relevant for health insurance providers and public health facilities, among others. A useful information is the probability distribution of influenza epidemics occurring within a time horizon of one or two years, say. We present a model that delivers confidence intervals for future influenza activity in different regions in the US. The model takes into account the specific statistical characteristics of influenza activity such as volatility clusters, seasonal effects, and dependencies between different regions. Confidence intervals for the regions are obtained using ARMA-GARCH models, regional dependencies are captured by a pair-copula construction, describing jointly the residuals of the ARMA-GARCH models. Our model allows to simulate influenza activity over a future time horizon.     «
