hhh4: An endemic-epidemic modelling framework for infectious disease counts

The R package surveillance provides tools for the visualization, modelling and monitoring of epidemic phenomena. This vignette is concerned with the hhh4 modelling framework for univariate and multivariate time series of infectious disease counts proposed by Held et al. (2005), and further extended by Paul et al. (2008), Paul and Held (2011), Held and Paul (2012), and Meyer and Held (2014). The implementation is illustrated using several built-in surveillance data sets. The special case of spatio-temporal hhh4 models is also covered in Meyer et al. (2017, Section 5), which is available as the extra vignette("hhh4_spacetime").
