Details

Heterogeneous Kernel set up

Infectious model is parameterised by a predefined kernel.

Removal process is independent of infectious process a posteriori

Hence no need to sample removal parameter, given we have chosen a suitable prior (i.e Exponential/Gamma)

Paired Infection-Removal times.

Initialise Calculate Infectious Process part of the likelihood (Removal Process will cancel out). Gamma Posterior Parameters Data Accept/Reject MCMC Plots
