Overview of the random forest regression (RF-R) results. A) Permutation error (feature importance) associated with each of the 20 features examined shown as mean OOBE and standard error across RF-R iterations. B) Group mean and standard error bars of age in years for those who passed (blue) and those who failed (orange) along each of the scans in the MRI sequence. The order of scan listed on the x-axis reflects the order in which scans were attempted during the MRI session following the sequence design shown in Fig. 2. As a note, scan 3 reflects two task blocks administered as detailed in Supplementary methods.
