Voxel-vise displacement-dependent groups.

Formation of voxel-wise displacement related groups. N = 105 healthy control patients were divided into group-pairs randomly, 5000 times. Eight pairs of groups were chosen so that correlation between the group-mean voxel-wise displacement maps () were 0.89, 0.9, 0.91, 0.92, 0.93, 0.94, 0.95 and 0.96. and denotes the mean ( standard deviation) FD of the group-pairs (in mm) and denotes the probability that the groups are identical regarding FD (obtained using permutation test). Max and max denotes the obtained maximal variance inflation factor (VIF) (throughout all connections) corresponding to the grouping factor, in models STD and STD+RDI, respectively. None of the groups introduce multicollinearity in the models. (however there is a slight difference between the FDs of the group-pairs with a spatial voxel-wise displacement correlation of 0.98).
