Spatial Scan Statistics for Models with Excess Zeros and Overdispersion
Content Type: Abstract
Spatial Scan Statistics [1] usually assume Poisson or Binomial distributed data, which is not adequate in many disease surveillance scenarios. For example, small areas distant from hospitals may exhibit a smaller number of cases than expected in… read more… For example, small areas distant from hospitals may exhibit a smaller number of cases than expected in those simple models. Also, underreporting may occur in underdeveloped regions, due to inefficient data … For example, small areas distant from hospitals may exhibit a smaller number of cases than expected in those … -
Adaptive Likelihood Ratio Methods for the Detection of Space-Time Disease Clusters
Content Type: Abstract
Data obtained through public health surveillance systems are used to detect and locate clusters of cases of diseases in space-time, which may indicate the occurrence of an outbreak or an epidemic. We present a methodology based on adaptive… read more… locate clusters of cases of diseases in space-time, which may indicate the occurrence of an outbreak or an epidemic. … clusters of cases of diseases in space- time, which may indicate the occurrence of an outbreak or an epidemic … disease clusters using scan statistic.
