Complex Demodulation: a novel time series methods for analysing seasonal infectious diseases

Hogan, Alexandra; Glass, Katie; Anderssen, Robert S

Description

Understanding how seasonal patterns change from year to year is important for the management of infectious disease epidemics. Here, we present a mathematical formalization of the application of complex demodulation, which has previously only been applied in an exploratory manner in the context of infectious diseases. This method extracts the changing amplitude and phase from seasonal data, allowing comparisons between the size and timing of yearly epidemics. We first validate the method using...[Show more]
