Figure 2 : Trace plots for parameters from final joint model.

Trace Trace plots show values that the parameter took during the runtime of the MCMC sampling until it reached convergence. Trace plots for parameters θ5-15 years, θ<5 years and θnet use not every night show that the M-H samplers explored the distribution by
traversing to areas where its density is very low with very small fluctuations, suggesting that the chains mixed well to the target distributions. In D, the sampling for the parameter of cumulative parasite count θcumulative shows noisy pattern before converging at about 1000 iterations.
