Visualization of 15-dimensional MCMC sample from prior, conditional and posterior probability density. A. Plot of sample drawn from prior probability density of Θφ(b3), p(Θφ). B. Plot of sample drawn from conditional probability density of Θφ(b3), . C. Plot of sample drawn from posterior probability density of Θφ(b3), . Each polyline represents hereby one point φk in the 15-dimensional density parameter space. The position of the vertex on the i-th dotted vertical line gives the value of the i-th density parameter. The color of the points indicates the logarithm of the unnormalized probability density of the data. Bright polylines (points φk) have a high posterior probability whereas dark polylines have a low posterior probability.
