Each panel corresponds to a model parameter as described in the main text: A) edges, B) temporal edges, C) temporal triangles, D) stability. MCMC diagnostics shown here are from the last round of simulation, prior to computation of final parameter estimates. In each panel the left side plot shows the MCMC sample statistics while the right plot shows the distribution of the difference between the observed and simulated values. MCMC sample statistics are varying randomly around the observed values at each step (so the chain is ���mixing��� well) and the difference between the observed and simulated values of the sample statistics have a roughly bell-shaped distribution, centered at 0. The sawtooth pattern visible on the degree term deviation plot is due to the combination of discrete values and small range in the statistics, so this is an inherent property of the statistic, not a problem with the fit (Hunter et al., 2008). As a side note, the same values were obtained for the model parameters when using MPLE instead of MCMCLE. |
