Fig. 7

Power spectral density (PSD) of Markov chains of nine model parameters. In each figure, red and blue show the results of RWMH and HMC, respectively. The light color line shows PDF and the heavy color line shows the moving average of PDF (the average of 25 points on the right and left side). The result of the log approximation is visually shown by the straight line and its estimated inclination is inserted on the bottom left of each figure (upper blue: HMC, lower red: RWMH)
