The top predictors for estimating RAVLT Percent Forgetting in all subjects (AD, MCI and NC). For each voxel, the average magnitude of the standardized regression coefficients (normalized with respect to the standard deviation of the response variable) across 100 different 10-fold CV iterations are calculated. The third column shows the number of voxels with the average magnitude greater than or equal to 0.01 in the corresponding region and the fourth column shows the maximum value of the average magnitude of regression coefficients with the region. The ranking is based on the maximum value of the average magnitude of regression coefficients within each region. The region definitions correspond to those of the AAL atlas and we abbreviate gyrus as G.
