Nonnormality of the distributions spanned by the males with ASD and those with Asperger's syndrome according to the DSM-IV column of ABIDE. (A) The left panel shows the frequency histograms for each ADOS-G subscore; the central panel shows the empirical CDF's fit by the theoretical normal and gamma family CDFs for the total score; and the right panel shows similar plots for the ADOS-2. (B) Same format as in panel A for the case of Asperger's syndrome. Notice the separation of CDFs between ADOS-G and ADOS-2 contrasting with those of the ASD cases in panel A.
