Figure 7.

MCMC chains and burn-in results of a single voxel (the voxel indicated in Figure 6) for the BallStick_in1 Fraction of Stick (FS) and the NODDI Fraction Restricted (FR) model parameters. In the first row, the sampling trace when starting at the MLE or at two default points with (only) a varying volume fraction. In the second row, moving mean and moving standard deviations computed over 1,000 samples with increasing burn-in. In the bottom row, autocorrelation plots computed over 1,000 samples, with the 99% confidence interval in dashed gray.
