Understanding multi-group (age-structure/spatial-structure) dynamics of infectious diseases is a fundamental issue for both scientific study and policy making. In particular, the question of how to define a data driven criteria for partitioning incidence data to specific groups has yet to been addressed. In this talk we present a statistical methodology for data-driven partitioning of infectious disease incidence into groups, and fitting a model to the resulting partition. Specifically, we present a methodology for building a hierarchical clustering tree and pruning it, leaving only significant age-group clusters in the partition, while controlling the familywise error rate. The partition algorithm is built on recent theoretical results on identifiability of parameters underlying the mechanistic models of epidemic dynamics. The methodology is tested using simulations and applied to infectious disease incidence data of seasonal influenza.
