In public health surveillance, accurate monitoring, analysis and prediction of disease counts are fundamental for effective and timely detection of disease outbreaks. Surveillance data usually appear in form of count time series.
Statistical analysis of this type of data is challenging because it combines difficulties related to modelling discrete data with the need to account for serial dependence.
The EU funded project SCouT aims at developing statistical tools able to balance competing needs for timeliness, model simplicity and effectiveness in outbreak detection.
The basic statistical tool used in SCouT is composite likelihood that follow the `divide and conquer principle’: split a complicated problem into simpler subproblems and then aggregate.
