Fig. 11.

The difference between the true value of each entry in each θ _k and the approximated marginal posterior distribution generated by the MCMC sampler in the large synthetic data experiment. The black dot represents the median and the vertical line goes between the 2.5 and 97.5 % quantiles. To get the axis on the same scale for all the clusters, they are scaled by the standard deviation of μ _k. The light gray horizontal line is the 0 line. The red dot and lines is the same however where one uses the true μ _k to estimate θ _k, rather then the μ _k obtained by taking the posterior means of the mixtures
