  • Detecting Coherent Structures in Syndromic Time Series Using Wavelets

    Content Type: Abstract

    Temporally localized outbreaks occur in the presence of a complex background, greatly complicating both retrospective and real-time detection. Numerous techniques have been proposed for adjusting thresholds to account for this variable background.… read more

  • Characterizing Repeated Outbreak Patterns in Influenza Time Series

    Content Type: Abstract

    In some influenza seasons, morbidity and mortality closely follow the expected seasonal variation. In these years, approaches such as Serflingís model and seasonal-based syndromic outbreak detectors, in use in EARS, work well. In other years,… read more
